"There are two days and two nights the likes of which no one has ever heard of before: the Day on which you will receive the news about Allâh the Exalted: whether you will receive His punishment or His mercy, the Day you will be given your book (of deeds): either in your right hand or your left, that [first] night you will spend alone in your grave, a night like no other you have spent, and that night on the morning of which will be the Day of Resurrection, after which there will be no more night."
Scholar: Anas ibn Mâlik
