1. Imam Ja’far Sadiq عليه السلام narrates from his predecessors that the Holy Prophet صلى الله عليه وعلى آله وسلم said, “One who performs four deeds, becomes deserving of a great light of Allah. They are: testifying that there is no Lord except Allah and I am His prophet, saying Innaa lillaahi wa innaa ilaihi raaji-oo’n at the time of difficulty, saying Alh’amdulillaah on hearing a good news and saying Astaghfirullaah on committing a sin.”
