Surah al-Baqarah (The Cow) 2 : 191

The below Ayat were revealed at a later stage, in Surah al-Fath (48). [further  research needed]

وَهُوَ الَّذِى كَفَّ أَيْدِيَهُمْ عَنكُمْ وَأَيْدِيَكُمْ عَنْهُم بِبَطْنِ مَكَّةَ مِن بَعْدِ أَنْ أَظْفَرَكُمْ عَلَيْهِمْ

"And He it is Who has withheld their hands from you and your hands from them in the midst of Makkah, after He had made you victors over them." (48:24) 

وَلَوْلاَ رِجَالٌ مُّؤْمِنُونَ وَنِسَآءٌ مُّؤْمِنَـتٌ لَّمْ تَعْلَمُوهُمْ أَن تَطَئُوهُمْ فَتُصِيبَكمْ مِّنْهُمْ مَّعَرَّةٌ بِغَيْرِ عِلْمٍ لِّيُدْخِلَ اللَّهُ فِى رَحْمَتِهِ مَن يَشَآءُ لَوْ تَزَيَّلُواْ لَعَذَّبْنَا الَّذِينَ كَفَرُواْ مِنْهُمْ عَذَاباً أَلِيماً

"Had there not been believing men and believing women whom you did not know, that you may kill them and on whose account a sin would have been committed by you without (your) knowledge, that Allah might bring into His mercy whom He wills ـ if they (the believers and the disbelievers) had been apart, We verily, would have punished those of them who disbelieved with painful torment." (48:25)

The scholars are unanimous that Surah al-Baqarah is Madani and that it was the first Surah revealed in Madinah. [Ibn Hajar al-Asqalani in Fath al-Bari no. 160/8].

Despite it being the first Surah to be revealed in Madinah, it contains Ayaat from a later period also. In fact, according to Ibn Abbas [as mentioned in Ibn Kathir] the last Ayat revealed to the Prophet was Ayat no. 281 from Surah al-Baqarah and this occurred 8 days or so before his death [which corresponds to the year 11 Hijri].

In order to understand the meaning of this Surah, we should know its historical background:

1. At Makkah, the Quran generally addressed the polytheist Quraysh who were ignorant of Islam, but at Madinah it was also concerned with the Jews who were acquainted with the creed of Monotheism, Prophethood, Revelation, the Hereafter and Angels. They also professed to believe in the law which was revealed by God to their Prophet Moses, and in principle, their way was the same (Islam) that was being taught by Prophet Muhammad. But they had strayed away from it during the centuries of degeneration and had adopted many un-Islamic creeds, rites and customs of which there was no mention and for which there was no sanction in the Torah. Not only this: they had tampered with the Torah by inserting their own explanations and interpretations into its text. They had distorted even that part of the Word of God which had remained intact in their Scriptures and taken out of it the real spirit of true religion and were now clinging to a lifeless frame of rituals. Consequently their beliefs, their morals and their conduct had gone to the lowest depths of degeneration. The pity is that they were not only satisfied with their condition but loved to cling to it. Besides this, they had no intention or inclination to accept any kind of reform. So they became bitter enemies of those who came to teach them the Right Way and did their utmost to defeat every such effort. Though they were originally Muslims, they had swerved from the real Islam and made innovations and alterations in it and had fallen victims to hair splitting and sectarianism. They had forgotten and forsaken God and begun to serve material wealth. So much so that they had even given up their original name “Muslim” and adopted the name “Jew” instead, and made religion the sole monopoly of the children of Israel. This was their religious condition when the Prophet went to Madinah and invited the Jews to the true religion. That is why more than one third of this Surah has been addressed to the children of Israel. A critical review of their history, their moral degeneration and their religious perversions has been made. Side by side with this, the high standard of morality and the fundamental principles of the pure religion have been put forward in order to bring out clearly the nature of the degeneration of the community of a prophet when it goes astray and to draw clear lines of demarcation between real piety and formalism, and the essentials and non-essentials of the true religion.

2. At Makkah, Islam was mainly concerned with the propagation of its fundamental principles and the moral training of its followers. But after the migration of the Prophet to Madinah, where Muslims had come to settle from all over Arabia and where a tiny Islamic State had been set up with the help of the ‘local supporters’ (Ansar), naturally the Quran had to turn its attention to the social, cultural, economic, political and legal problems as well. This accounts for the difference between the themes of the Surahs revealed at Makkah and those at Madinah. Accordingly about half of this Surah deals with those principles and regulations which are essential for the integration and solidarity of a community and for the solution of its problems.

After the migration to Madinah, the struggle between Islam and disbelief (Kufr) had also entered a new phase. Before this the Believers, who propagated Islam among their own clans and tribes, had to face its opponents at their own risk. But the conditions had changed at Madinah, where Muslims from all parts of Arabia had come and settled as one community, and had established an independent city state. Here it became a struggle for the survival of the Community itself, for the whole of non-Muslim Arabia was bent upon and united in crushing it totally. Hence the following instructions, upon which depended not only its success but its very survival, were revealed in this Surah:

a. The Community should work with the utmost zeal to propagate its ideology and win over to its side the greatest possible number of people.

b. It should so expose its opponents as to leave no room for doubt in the mind of any sensible person that they were adhering to an absolutely wrong position.

c. It should infuse in its members (the majority of whom were homeless and indigent and surrounded on all sides by enemies) that courage and fortitude which is so indispensable to their very existence in the adverse circumstances in which they were struggling and to prepare them to face these boldly.

d. It should also keep them ready and prepared to meet any armed menace, which might come from any side to suppress and crush their ideology, and to oppose it tooth and nail without minding the overwhelming numerical strength and the material resources of its enemies.

e. It should also create in them that courage which is needed for the eradication of evil ways and for the establishment of the Islamic Way instead. That is why God has revealed in this Surah such instructions as may help achieve all the above mentioned objects.

At the time of the revelation of Al-Baqarah, all sorts of hypocrites had begun to appear. God has, therefore, briefly pointed out their characteristics here. Afterwards when their evil characteristics and mischievous deeds became manifest, God sent detailed instructions about them. [REF: Mawdudi]

• The Prophet is reported to have said:
   إنَّ هَذَا الْبَلَدَ حَرَّمَهُ اللهُ يَوْمَ خَلَقَ السَّموَاتِ وَالْأَرْضَ، فَهُوَ حَرَامٌ بِحُرْمَةِ اللهِ إِلى يَوْمِ الْقِيَامَةِ، وَلَمْ يَحِلَّ لِي إِلَّا سَاعَةً مِنْ نَهَارٍ، وَإِنَّهَا سَاعَتِي هذِهِ حَرامٌ بحُرْمَةِ اللهِ إِلى يَوْمِ الْقِيامَةِ، لا يُعْضَدُ شَجَرُهُ، وَلَا يُخْتَلىَ خَلَاهُ، فَإِنْ أَحَدٌ تَرَخَّصَ بِقِتَالِ رَسُولِ اللهِصلى الله عليه وسلّم، فَقُولُوا: إنَّ اللهَ أَذِنَ لِرَسُولِهِ وَلَمْ يَأْذَنْ لَكُم
  
  "Allah has made this city a sanctuary since the day He created the heavens and the earth. So, it is a sanctuary by Allah's decree till the Day of Resurrection. Fighting in it was made legal for me only for an hour in the daytime. So, it (i.e., Makkah) is a sanctuary, by Allah's decree, from now on until the Day of Resurrection. Its trees should not be cut, and its grass should not be uprooted. If anyone mentions the fighting in it that occurred by Allah's Messenger, then say that Allah allowed His Messenger, but did not allow you." [Bukhari and Muslim]

• Buraydah narrated that Allah's Messenger said: اغْزُوا فِي سَبِيلِ اللهِ، قَاتِلُوا مَنْ كَفَرَ بِاللهِ، اغْزُوا وَلَا تَغُلُّوا وَلَا تَغْدِرُوا وَلَا تَمْثُلُوا وَلَا تَقْتُلُوا وَلِيدًا وَلَا أَصْحَابَ الصَّوَامِع

  "Fight for the sake of Allah and fight those who disbelieve in Allah. Fight, but do not steal (from the captured goods), commit treachery, mutilate (the dead), or kill a child, or those who reside in houses of worship." [Sahih Muslim]

• Ibn `Umar said, "A woman was found dead during one of the Prophet's battles and the Prophet then forbade killing women and children. '' [Bukhari and Muslim]

• Allah has made this city a sanctuary since the day He created the heavens and the earth. So, it is a sanctuary by Allah's decree till the Day of Resurrection. Fighting in it was made legal for me only for an hour in the daytime. So, it (i.e., Makkah) is a sanctuary, by Allah's decree, from now on until the Day of Resurrection. Its trees should not be cut, and its grass should not be uprooted. If anyone mentions the fighting in it that occurred by Allah's Messenger, then say that Allah allowed His Messenger, but did not allow you.
  [Bukhari and Muslim]

• Abu Musa Al-Ash`ari said: "The Prophet was asked, `O Allah's Messenger! A man fights out of bravery, and another fights to show off, which of them fights in the cause of Allah' The Prophet said, He who fights so that Allah's Word is superior, then he fights in Allah's cause. 
  [Bukhari and Muslim]

• I have been ordered (by Allah) to fight the people until they proclaim, `None has the right to be worshipped but Allah'. Whoever said it, then he will save his life and property from me, except for cases of the law, and their account will be with Allah.
  [Bukhari and Muslim]
