The Book of the Believer · Hadith 145 (#Ḥadīth #39)

145- وعن أبي عبد الله عليه السلام قال: من أعان أخاه المؤمن اللهبان اللهفان عند جهده فنفس كربه وأعانه على نجاح حاجته، كانت له بذلك اثنان وسبعون رحمة من الله عز وجل يعجل له منها واحدة يصلح بها أمر معيشته، و يدخر له واحدة وسبعين رحمة لوائج القيامة ، وأهوالها

145. It has been reported that Abu 'Abd Allah said: One who helps his grieving and distressed fellow believer in his struggle, relieves his distress and helps him in attaining his need shall have seventy-two mercies from Allah; one of which is hastened to him to improve his livelihood, and the remaining seventy-one mercies are stored away for him for the woes of the Resurrection and its horrors.
