1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn al-Hakam from Hisham ibn Salim from Abu ‘Abdillah عليه السلام who has said the following: “Whoever prays and pleads before Allah for help before the fall of misfortune, his prayer is accepted when the misfortune arrives. The angels will say, ‘It is a known voice and it is not barred from heaven. ’ If one does not pray and plead before Allah for help before the fall of misfortune, his prayer will not be accepted when it falls upon him. The angels will say, ‘We do not know this voice.’”
