عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: ’’إِذَا نَعَسَ أَحَدُكُمْ فِي الصَّلاَةِ فَلْيَنَمْ حَتَّى يَعْلَمَ مَا يَقْرَأُ‘‘.
Hazrat Anasra narrated, “The Prophetsa said, ‘When any one of you becomes drowsy in prayer, let him lie down and sleep until he is aware of what he is reciting.’”
