Sunan Ibn Majah Book 5, Hadith 1044

حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، حَدَّثَنَا عَبْدُ الأَعْلَى، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ صَلَّى رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَوْمًا بِأَصْحَابِهِ فَلَمَّا قَضَى الصَّلاَةَ أَقْبَلَ عَلَى الْقَوْمِ بِوَجْهِهِ فَقَالَ ‏"‏ مَا بَالُ أَقْوَامٍ يَرْفَعُونَ أَبْصَارَهُمْ إِلَى السَّمَاءِ ‏"‏ ‏.‏ حَتَّى اشْتَدَّ قَوْلُهُ فِي ذَلِكَ ‏"‏ لَيَنْتَهُنَّ عَنْ ذَلِكَ أَوْ لَيَخْطَفَنَّ اللَّهُ أَبْصَارَهُمْ ‏"‏ ‏.‏

It was narrated that Anas bin Malik said:“The Messenger of Allah (ﷺ) led his Companions in prayer one day. When he had finished prayer he turned to face the people and said: ‘What is wrong with some people that they lift their gaze to the heavens?’ He spoke severely concerning that: ‘They should certainly abstain from that or Allah will snatch away their sight.’”
