The Book of the Believer · Hadith 137 (#Ḥadīth #31)

137- وعن أبي عبد الله عليه السلام قال: قال النبي صلى الله عليه وآله وسلم: من أعان أخاه اللهفان اللهبان من غم أو كربة كتب الله عز وجل له إثنين وسبعين رحمة، عجل له منها واحدة يصلح بها أمر دنياه، واحدة وسبعين لأهوال الآخرة

137. It has been reported that Abu 'Abd Allah said: The Prophet said: Whoever relieves his grieving brother from a sorrow or distress, Allah will record for him seventy-two mercies; of them, one He shall hasten to him in this world in order to improve his worldly affairs, and seventy-one (will be postponed) to alleviate the horrors of the hereafter.”
