From Ibn Abbas (RadhiAllaahu anhu) that a man came to him and said: ‘I proposed to a woman but she refused to marry me, someone else proposed to her and she liked him and married him. I became jealous over her and I killed her, can I repent from this?’
Ibn ‘Abbas asked: ‘Is your mother alive?’
He answered: ‘No.’
Then Ibn Abbas said: ‘Repent to Allaah –Azza wa Jal- and come close to Him as much as you can.’
The narrator said: I went and asked Ibn ‘Abbas (RadhiAllaahu anhu): ‘Why did you ask him whether his mother was alive?’
Ibn Abbas (RadhiAllaahu anhu) answered: ‘Indeed I do not know of an action closer to Allaah –Azza wa Jal- than being good to one’s mother.’
