And that the Prophet (peace and blessings be upon him) said: "Whoever has one of three qualities, Allah will marry him to whomever (he wishes) of the wide-eyed maidens of Paradise (al-Hur al-'In): one who has a hidden trust that he is tempted by and fulfils it out of fear of Allah, or a man who forgives his killer, or a man who recites 'Qul huwa Allahu ahad' (Say: He is Allah, the One) after every prayer."
