The Messenger of Allah ﷺ said, "Whoever eases the hardship of one in difficulty, Allah will ease his affairs in this world and the next."
حدثنا أبو بكر بن أبي شيبة حدثنا أبو معاوية عن الأعمش عن أبي صالح
قال رسول الله ﷺ من يسر على معسر يسر الله عليه في الدنيا والآخرة
Muslim narrated it in "The Book of Remembrance and Supplication," chapter on the merit of gathering for the recitation of the Quran and for remembrance, hadith no. 2699, from the hadith of Abu Muawiya in full, and Amash stated explicitly that he heard it there.
