Riyad as-Salihin, Book 18, Hadith 1611 (In-Book) ⓘ
Abu Hurairah (May Allah be pleased with him) said: The Messenger of Allah said, "It is an act of oppression on the part of a person to procrastinate in fulfilling his obligation; if the repayment of a debt due to any of you is undertaken by a rich person, you should agree to the substitution."[Al-Bukhari and Muslim].
وعن أبي هريرة رضي الله عنه أن رسول الله صلى الله عليه وسلم قال: "مطل الغني ظلم وإذا أُتبع أحدكم على مليء فليتبع" ((متفق عليه. معنى "أتبع": أحيل)).
