Sunan an-Nasa'i, Book 34, Hadith 17 (In-Book) ⓘ
Ibn Juraij said: "Abu Az-Zubair informed me that he heard Jabir saying: 'The Messenger of Allah said: "Whoever is given something on the basis of 'Umra it belongs to him for the rest of his life and after he dies."'"
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا أَبُو عَاصِمٍ، قَالَ حَدَّثَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرًا، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أُعْمِرَ شَيْئًا فَهُوَ لَهُ حَيَاتَهُ وَمَمَاتَهُ " .
