" لَيَنْتَهِيَنَّ أَقْوَامٌ عَنْ رَفْعِ أَبْصَارِهِمْ عِنْدَ الدُّعَاءِ فِي الصَّلاَةِ إِلَى السَّمَاءِ أَوْ لَتُخْطَفَنَّ أَبْصَارُهُمْ "
It was narrated from Abu Hurairah that: The Messenger of Allah (ﷺ) said: "People should certainly stop lifting their gaze to the sky when they supplicate during the prayer, or they will lose their eyesight."
