Surah al-Baqarah (The Cow) 2 : 232

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].

Al-Tirmidhī reported that Ma`qil ibn Yasār gave his sister in marriage to a Muslim man who later divorced her and she remained divorced until her waiting period had elapsed. After some time they both felt they would like to marry again and the man went to Ma`qil, asking to marry her. Ma`qil was furious and reprimanded the man for divorcing her in the first place, and swore that he would never marry her if he were to live for ever. Al-Tirmidhī adds that, nevertheless, it was God’s will that the couple should have the chance to be reunited. Thus, this verse was revealed. On hearing it, Ma`qil said: “I hear and I obey.” He then called the man and said to him: “You have my blessings to marry her.”

This highly compassionate divine gesture towards people’s feelings and emotions is evidence of God’s boundless mercy towards mankind. The verse as a whole aims to mitigate the trauma of divorce and to educate Muslims in organizing their social affairs realistically and with compassion.
