Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا أَبَانُ الْعَطَّارُ حَدَّثَنَا قَتَادَةُ عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا بَالُ أَقْوَامٍ يَرْفَعُونَ أَبْصَارَهُمْ إِلَى السَّمَاءِ فِي صَلَاتِهِمْ فَاشْتَدَّ قَوْلُهُ فِي ذَلِكَ حَتَّى قَالَ لَيَنْتَهُنَّ عَنْ ذَلِكَ أَوْ لَتُخْطَفَنَّ أَبْصَارُهُمْ.
English Translation
Affan told us: Aban al-Attar told us: Qatada told us, from Anas, that the Prophet, peace and blessings be upon him, said: "What is the matter with people who raise their eyes to the sky during their prayer?" His words on that grew stern, until he said: "Let them stop that, or their sight will surely be snatched away."
