عن أنس بن مالك
قَالَ: قَالَ رسولُ اللهِ: «مَا بَالُ أقْوامٍ يَرْفَعُونَ أبْصَارَهُمْ إِلَى السَّمَاءِ في صَلَاتِهِمْ»! فَاشْتَدَّ قَولُهُ في ذَلِكَ حَتَّى قَالَ: «لَيَنْتَهُنَّ عَنْ ذَلِكَ، أَوْ لَتُخطفَنَّ أَبْصَارُهُمْ»!
The Messenger of Allah (sallallahu alayhi wa sallam) said, “How is it that some people raise their eyes towards the sky during As-Salat (the prayer)?” He stressed (this point) and added, “People must refrain from raising their eyes towards heaven in Salat (prayer), or else their sights will certainly be snatched away.”.
