قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«لَيَنْتَهِيَنَّ قَوْمٌ يَرْفَعُونَ أَبْصَارَهُمْ إِلَى اَلسَّمَاءِ فِي اَلصَّلَاةِ أَوْ لَا تَرْجِعَ إِلَيْهِمْ» رَوَاهُ مُسْلِمٌ. 11 صحيح
The Messenger of Allah (sallallahu alayhi wa sallam) said: “Those people who raise their eyes to heaven while in Salat (prayer) should stop (doing so) or else their sight will not return to them.”.
