- ﵁ - - ﷺ:
Anas ibn Mālik (may Allah be pleased with him) said: The Messenger of Allah ﷺ said: "What is the matter with people who raise their eyes to the sky in their prayer!" His words on this grew severe, until he said: "They must surely desist from that, or their sight will surely be snatched away!" Narrated by al-Bukhārī.
