'There are ten signs of a righteous person: he loves for the sake of Allah, hates for the sake of Allah, befriends for the sake of Allah, abandons for the sake of Allah. He becomes angry for the sake of Allah, becomes pleased for the sake of Allah, works for the sake of Allah, beseeches Allah, submits to Allah fearing Him, awed [by others], pure, sincere, bashful, and watchful and acts kindly for the sake of Allah.'
