"The Messenger of Allah said: 'If one of you is referred to a rich man (to help repay a debt), he should accept that referral, and (wrongdoing) is when a rich man takes a long time to repay a debt."' (Using translation from Nasāʾī 4688)
عَنِ النَّبِيِّ ﷺ؟ قَالَ نَعَمْ الْمَطْلُ ظُلْمُ الْغَنِيِّ وَإِذَا أُتْبِعَ أَحَدُكُمْ عَلَى مَلِيءٍ فَلْيَتْبَعْ
