Sahih Muslim , Book 22, Hadith 41 (In-Book)

Abu Huraira (Allah be pleased with him) reported Allah's Messenger as saying: Delay (in the payment of debt) on the part of a rich man is injustice, and when one of you is retired to a rich man, he should follow him.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، ‏.‏ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَطْلُ الْغَنِيِّ ظُلْمٌ وَإِذَا أُتْبِعَ أَحَدُكُمْ عَلَى مَلِيءٍ فَلْيَتْبَعْ ‏" ‏ ‏.‏
