Sunan an-Nasa'i, Book 34, Hadith 13 (In-Book) ⓘ
Sufyan narrated from Ibn Juraij, from 'Ata', from Jabir that the Messenger of Allah said: "Do not give things on the basis of Ruqba or 'Umra. Whoever is given something on the basis of Ruqba or 'Umra, it belongs to his heirs."
أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ يَزِيدَ، عَنْ سُفْيَانَ، عَنِ ابْنِ جُرَيْجٍ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ تُرْقِبُوا وَلاَ تُعْمِرُوا فَمَنْ أُرْقِبَ أَوْ أُعْمِرَ شَيْئًا فَهُوَ لِوَرَثَتِهِ " .
