Takhrij Hadith 1839: "O 'Ali, do not follow…"
On the authority of Buraydah ibn al-Husayb (may Allah be pleased with him), who said: The Messenger of Allah (peace and blessings be upon him) said to 'Ali (may Allah be pleased with him):
“
O 'Ali, do not follow one glance with another; for the first one is [excused for] you, but the next one is not.”
