The Hadith: 'Anyone who recites Ayat-ul-Kursy after each Salah'

Q: It is related on the authority of Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: Anyone who recites Ayat-ul-Kursy (the Qur'anic Verse of Allah's Chair, Surah Al-Baqarah, 2:255) after each Salah (Prayer) will have nothing to stand between them and entering Jannah (Paradise) except death. Was this Hadith authentically reported from the Prophet (peace be upon him)?

A: Al-Nasa'y and Ibn Hibban related on the authority of Abu Umamah (may Allah be pleased with him) that the Prophet (peace be upon him) said: Anyone who recites Ayat-ul-Kursy after each obligatory Salah will have nothing to stand between them and entering Jannah except death. This Hadith was only narrated by Muhammad ibn Humayd in some point in the chain of narration.It has several chains of narration which enhance one another. This means that the Hadith has an origin in religion. Ibn Al-Qayyim (may Allah be merciful to him) said: "It was related from several chains of narrators, but they are all weak. If they are combined, despite the different chains of narrators (Part No. 3; Page No. 214) and their verifiers, this will confirm that the Hadith has an origin in religion."May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
