The narrator asked Imam Musa Kadhim (a.s.), “What is the reward of offering Salaat-e-Ja’far-e-Tayyar?” Imam (a.s.) replied, “Allah would forgive that person even if his sins are equal to the number of grains of sand or number of waves in the oceans.” The narrator asked, “Is this reward applicable for us?” Imam (a.s.) replied, “Of course, then for whom else? It is for you only.” The narrator asked, “Which Surah should be recited in this Salaat?” Imam (a.s.) replied, “Recite Idhaa zulzilat, idhaa jaa-a nas’rullaah, innaa anzalnaahu fee lailatil qadr and qul huwallaahu ah’ad.”
