Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ حَدَّثَنَا سَعِيدُ بْنُ أَبِي عَرُوبَةَ عَنْ قَتَادَةَ عَنْ أَنَسِ بْنِ مَالِكٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ مَا بَالُ أَقْوَامٍ يَرْفَعُونَ أَبْصَارَهُمْ إِلَى السَّمَاءِ فِي صَلَاتِهِمْ قَالَ فَاشْتَدَّ قَوْلُهُ فِي ذَلِكَ حَتَّى قَالَ لَيَنْتَهُنَّ عَنْ ذَلِكَ أَوْ لَتُخْطَفَنَّ أَبْصَارُهُمْ.
English Translation
Muhammad ibn Bishr narrated to us: Sa'id ibn Abi 'Aruba narrated to us, from Qatada, from Anas ibn Malik, from the Prophet, peace and blessings be upon him, that he said: "What is the matter with people who raise their eyes to the sky during their prayer?" His words on this became stern until he said: "Let them stop that, or their sight will surely be snatched away."
