Muwatta Malik 1372
Business Transactions
حَدَّثَنَا يَحْيَى، عَنْ 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 .
Yahya related to me from Malik from Abu'z-Zinad from al Araj from Abu Hurayra that the Messenger of Allah, (ﷺ), said, "Delay in payment by a rich man is injustice, but when one of you is referred for payment to a wealthy man, let him be referred."
