It is likewise recommended to recite Āyat al-Kursī, based on the hadith of Abū Umāmah, may Allah be pleased with him, who said that the Messenger of Allah, may Allah bless him and grant him peace, said: “Whoever recites Āyat al-Kursī after every obligatory prayer, nothing prevents him from entering Paradise except death.” Reported by al-Nasā’ī in Amal al-Yawm wa al-Laylah.1
What is meant by his words, “nothing prevents him from entering Paradise except death,” is that nothing stands between him and entry into Paradise other than death.
Ibn al-Qayyim, may Allah have mercy on him, said: “I was informed that our shaykh, Abū al-Abbās Ibn Taymiyyah—may Allah sanctify his soul—said: ‘I never neglected to recite it after any prayer.’”2
It is also prescribed for a Muslim to say at the end of the prayers what the Prophet, may Allah bless him and grant him peace, advised Muādh ibn Jabal, may Allah be pleased with him, to say. Abū Dāwūd, al-Nasā’ī, and others relate from Muādh ibn Jabal, may Allah be pleased with him, that “the Messenger of Allah, may Allah bless him and grant him peace, took him by the hand one day and said: ‘O Muādh, by Allah, I love you. I counsel you, O Muādh: never fail to say at the end of every prayer, “O Allah, help me to remember You, give thanks to You, and worship You well.”’”3 Scholars hold two views as to whether this supplication should be said before the closing salām or afterward. Shaykh al-Islam favored saying it before the salām. Allah Most High knows best.
