"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."'" (Using translation from Nasāʾī 3735)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ أُعْمِرَ شَيْئًا فَهُوَ لَهُ حَيَاتَهُ وَمَمَاتَهُ»
