Hadith 1616
أَخْبَرَنَا مُحَمَّدُ بْنُ إِبْرَاهِيمَ الْبَصْرِيُّ، عَنْ بِشْرٍ، - هُوَ ابْنُ الْمُفَضَّلِ - قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَشْعَثَ بْنِ سُلَيْمٍ، عَنْ أَبِيهِ، عَنْ مَسْرُوقٍ، قَالَ قُلْتُ لِعَائِشَةَ أَىُّ الأَعْمَالِ أَحَبُّ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَتِ الدَّائِمُ . قُلْتُ فَأَىُّ اللَّيْلِ كَانَ يَقُومُ قَالَتْ إِذَا سَمِعَ الصَّارِخَ .
It was narrated that Masruq said:
"I said to 'Aishah: 'Which deed was most beloved to the Messenger of Allah (ﷺ)?' She said: 'That which was done persistently.' I said: 'At what part of the night did he pray Qiyam?' She said: 'When he heard the rooster.'"
