← Previous Hadith “I heard Abu Sa’d, a man from the people of Madinah, say: ‘I saw Abu Rafi’, the freed slave of the Messenger of Allah (ﷺ), when he saw Hasan bin ‘Ali performing prayer, with his hair braided. He undid it, or told him not to do that, and said: “The Messenger of Allah (ﷺ) forbade a man from performing prayer with his hair braided.”

Sunan Ibn Majah Book 5, Hadith 240 Next Hadith → “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.’”
