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. (In another version, the words are):" Yahya said: I think it was due to the regard for the Apostle of Allah ﷺ."

وَحَدَّثَنَا 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 ﷺ .
