Hadith.2751 - It is narrated from Hammad ibn Uthman, who said
A man said to Imam Abu Abdullah (as), "May I be your ransom! After completing my rituals for ‘Umrah, I went to my wife but had not trimmed my hair."
Imam (as) said: "You must offer a camel as expiation."
The man then said: "When I attempted this with her, and she had not trimmed her hair either, she resisted. When I overpowered her, she bit off some of her hair with her teeth."
Imam (as) said: "May Allah (swt) have mercy on her. She was more understanding of the matter than you. You must offer a camel as expiation, but nothing is required of her."
