It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that on the day of Arafah, so-and-so (Fadl) was riding behind the Prophet (peace and blessings be upon him). He was a young man and began to look at women. The Prophet (peace and blessings be upon him) turned his face away several times with his blessed hand, but he still kept glancing at them from the corner of his eyes. Upon this, the Prophet (peace and blessings be upon him) said: "Nephew! Today is such a day that whoever safeguards his ears, his eyes, and his tongue in it, Allah will forgive his sins."
