I heard years back in a hadith about russallah Saw asking Ali Rd, if he had completed 10 things before he went to bed (one being ?? amount of salah ). Ali Rd replied no as it was a lot to do in one day so, Russallah Saw advised him to recite such and such surahs, ayats and he would get the same reward.
I vaguely remember the story and have been looking for it for along time. Can someone please post it if the know or have it. Jazakallahu khiran.
