Virtues of Reciting AYAT UL KURSI after Salah

https://quran.com/2/255

Rasulallah (peace be upon him) said: “Whoever recites Aayatul Kursi after every Fard (Fard Salat). Only death is keeping him/her from entering Jannah. (As soon as he/she dies, will enter Jannah) (Nisa’i, Ibne Habban, Ibnelsani A’n Abi Amatah Albahili Radiallah Anhu)

Another Hadith states that Reciting Ayatul Kursi after one Fard (Fard Salat) will cause a person to stay in Allah’s protection until the next Salat. (Tibrani Fil Kabeer)
