عَنْ مَسْرُوقٍ قَالَ: سَأَلْتُ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا عَنْ صَلَاةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِاللَّيْلِ، فَقَالَتْ: كَانَ إِذَا سَمِعَ الصَّارِخَ قَامَ فَصَلَّى
Masruq says: I asked Sayyida Aisha (may Allah be pleased with her) about the night prayer of the Noble Prophet (peace and blessings be upon him), so she said: When he (peace and blessings be upon him) heard the crowing of the rooster, he would get up and perform prayer.
