It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "There are three things: whoever comes with them along with faith will enter Paradise by whichever of its gates he wishes, and will be married to as many of the wide-eyed houris as he wishes: one who pays off a hidden debt, one who forgives his killer, and one who recites ten times after every obligatory prayer 'Say: He is Allah, the One' (Surah al-Ikhlas)." Sayyiduna Abu Bakr (may Allah be pleased with him) said: "O Messenger of Allah, or even one of them?" He (peace and blessings be upon him) said: "Or even one of them."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated only with this chain, and Bishr bin Mansur is alone in narrating it."
