Sahih Muslim 9849
In-book no 2572وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا بِشْرُ بْنُ عُمَرَ الزَّهْرَانِيُّ، حَدَّثَنِي سُلَيْمَانُ، بْنُ بِلاَلٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، بِهَذَا الإِسْنَادِ غَيْرَ أَنَّهُ قَالَ وَذَلِكَ لِمَكَانِ رَسُولِ اللَّهِ صلى الله عليه وسلم .
This hadith is narrated on the authority of Yahya b. Sa'id with the same chain of transmitters but with this variation that he said that ('A'isha did not observe fast but in Sha'ban) out of regard for the Messenger of Allah (ﷺ).
