Narrated `Aisha:
حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا الأَعْمَشُ ، حَدَّثَنَا مُسْلِمٌ ، عَنْ مَسْرُوقٍ ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ لَمَّا نَزَلَتِ الآيَاتُ مِنْ آخِرِ سُورَةِ الْبَقَرَةِ فِي الرِّبَا قَرَأَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى النَّاسِ، ثُمَّ حَرَّمَ التِّجَارَةَ فِي الْخَمْرِ.
When the Verses of Surat-al-Baqara regarding usury (i.e. Riba) were revealed, Allah's Messenger (ﷺ) recited them before the people and then he prohibited the trade of alcoholic liquors.
