Al-Matalib al-'Aliyah 542 — What is said after the prayer

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 deeds such that whoever comes with them (into the presence of Allah) along with faith will enter Paradise by whichever of its gates he wishes, and will be married to whichever of the wide-eyed maidens (hur al-'in) he wishes: (first) the one who forgave his killer; (second) the one who paid off a hidden debt; and (third) the one who recited 'Say: He is Allah, the One' [Surah al-Ikhlas: 1] after every obligatory prayer." At this Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) asked: "O Messenger of Allah! Will this same virtue be given even for doing any one of them?" He (peace and blessings be upon him) said: "Yes, this same reward will be given even for doing any one of them."
Abu Ya'la recorded this hadith in his Musnad (542); its chain contains a narrator named Umar bin Nabhan, who is da'if (weak).
