The Messenger of Allah ﷺ said, "Whoever recites Ayat al-Kursi after every obligatory prayer, nothing prevents him from entering Paradise except death."
قال رسول الله ﷺ: من قرأ آية الكرسي في دبر كل صلاة مكتوبة لم يمنعه من دخول الجنة إلا أن يموت.
Nasai narrated it in Al-Yawm wal-Laylah (100) from Husayn bin Bishr, who said, Muhammad bin Himyar told us, who said, Muhammad bin Ziyad told us, from Abu Umama, and he mentioned the hadith. Its isnad is hasan because of Muhammad bin Himyar, for he is hasan al-hadith, and this was mentioned earlier in the book of Supplications and Remembrances.As for what was narrated from Anas as a raised report, "The Verse of the Throne is a quarter of the Quran," this is daif. Ahmad narrated it (13309) from Abdullah bin Harith, who said, Salama bin Wardan told me, from Anas bin Malik, and he mentioned it. Tirmidhi narrated it (2895) through another route from Salama bin Wardan, but he did not mention the Verse of the Throne, and the hadith contains a story. Its isnad is daif because of Salama bin Wardan al-Laythi al-Madani, who is daif by the agreement of the scholars, and Ibn Hibban said, He narrates from Anas things that do not resemble his hadith.
