Some verses to recite after Namaz along with their rewards
Hazrat Imam Jafar Sadiq (a.s.) says:
When Allah commanded Ayatul Kursi, Ayat Shahadat, Ayat Mulk to descend upon the earth, those verses said: O Lord, are You sending us towards sinful erring people!!? Then Haq Ta’ala said there: You go upon the earth, I swear by My honor and majesty that whoever from Aal-e-Mohammad (s.a.w.w.) and their Shia recites you, then I will cast seventy glances of mercy towards him from My hidden mercies and accept his repentance. Even if he has major sins.
And in the narration it is that Allah said:
Whoever recites these verses after every obligatory (wajib) Namaz, then I will place him at the place named “Hazira-e-Quddus”. Even if he has committed any kind of sins. If I do not do so, then I will look towards him with My special mercy and if even that I do not do, then I will fulfill seventy of his needs wherein the smallest need is not to punish for minor sins. If even that I do not do then I will keep him under My sanctuary from the harm of every enemy and help him against his enemies and nothing except death will come in the way of his entry into Paradise and those verses are “Surah Alhamd, Ayatul Kursi, Ayat Shahadat and Ayat Mulk”.
