5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Sayf ibn ‘Amirah from Sa‘d al-Iskaf who has said the following: “Abu Ja‘far, ‘Alayhi al-Salam, has said, ‘Once a young man from al-Ansar (people of al-Madinah) came face to face with a woman in al-Madinah. Women would wear their scarf behind their ears. He looked at her when she was coming, and when she passed by he kept looking, and she entered in an alley that he called alley of so and so people. He kept looking behind her until his face hit a piece of bone or glass in the wall which caused a deep cut on his face. When the woman went away he found blood flowing on his chest and clothes and he said, ‘By Allah, I will go and tell it to the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause.’ He (the Imam) said that he went to him (the Messenger of Allah) and when he (the Messenger of Allah) saw him, he (the Messenger of Allah) asked, ‘What has happened to you?’ He inform him (the Messenger of Allah) and Jibril came with this verse, ‘Tell the believers to cast down their eyes and protect their genital organs (against indecent acts), it is more clean for them; Allah is well aware of what they do.’” (24:31)
