عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((إِذَا نَعَسَ أَحَدُكُمْ فِي الْمَسْجِدِ يَوْمَ الْجُمُعَةِ فَلْيَتَحَوَّلْ مِنْ مَجْلِسِهِ ذَلِكَ إِلَى غَيْرِهِ))
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When any of you feels sleepy in the mosque on the day of Jumu’ah, he should move from his place and sit somewhere else.
