Muwatta Malik 461

Arabic

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ قَالَ صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم بَعْدَ أَنْ قَدِمَ الْمَدِينَةَ سِتَّةَ عَشَرَ شَهْرًا نَحْوَ بَيْتِ الْمَقْدِسِ ثُمَّ حُوِّلَتِ الْقِبْلَةُ قَبْلَ بَدْرٍ بِشَهْرَيْنِ ‏.‏

Translation

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "The Messenger of Allah, may Allah bless him and grant him peace, prayed towards the Baytal-Maqdis for sixteen months after arriving in Madina. Then the qibla was moved, two months before the battle of Badr
