Surah al-Baqarah (The Cow) 2 : 126

• رَّبَّنَا إِنِّي أَسْكَنتُ مِن ذُرِّيَّتِي بِوَادٍ غَيْرِ ذِي زَرْعٍ عِندَ بَيْتِكَ الْمُحَرَّمِ رَبَّنَا لِيُقِيمُوا الصَّلَاةَ فَاجْعَلْ أَفْئِدَةً مِّنَ النَّاسِ تَهْوِي إِلَيْهِمْ وَارْزُقْهُم مِّنَ الثَّمَرَاتِ لَعَلَّهُمْ يَشْكُرُونَ
  
  "Our Lord, I have settled some of my descendants in an uncultivated valley near Your sacred House, our Lord, that they may establish prayer. So make hearts among the people incline toward them and provide for them from the fruits that they might be grateful." (14:37) 

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 Messenger of Allah said, 'Ibrahim made Allah's House a Sacred Area and a safe refuge. I have made what is between the two sides of Al-Madinah a Sacred Area. Therefore, its game should not be hunted, and its trees should not be cut.' An-Nasa'i and Sahih Muslim also recorded this Hadith.
• `Abdullah bin `Abbas saying that the Messenger of Allah said 'Allah has made this city a sanctuary (sacred place) the Day He created the heavens and earth. Therefore, it is a sanctuary until the Day of Resurrection because Allah made it a sanctuary. It was not legal for anyone to fight in it before me, and it was legal for me for a few hours of one day. Therefore, it is a sanctuary until the Day of Resurrection, because Allah made it a sanctuary. None is allowed to uproot its thorny shrubs, or to chase its game, or to pick up something that has fallen, except by a person who announces it publicly, nor should any of its trees be cut.) Al-`Abbas said, `O Messenger of Allah! Except the lemon-grass, for our goldsmiths and for our graves.' The Prophet added, (Except lemon-grass.) This is the wording of Muslim. The Two Sahihs also recorded Abu Hurayrah narrating a similar Hadith, while Al-Bukhari recorded a similar Hadith from Safiyyah bint Shaybah who narrated it from the Prophet . 
• Jabir said that the Messenger of Allah said, 'No one is allowed to carry weapons in Makkah' Sahih Muslim.
• Abu Hurayrah said that the Messenger of Allah said, 'When the son of Adam dies, his deeds end except for three deeds: an ongoing charity, a knowledge that is being benefited from and a righteous son who supplicates (to Allah) for him.' Sahih Muslim
