(A different chain) from Abu 'Amr, from Ibn Shihab, from Abu Salamah, from Jabir, who said:"The Messenger of Allah said: 'Umra (a lifelong gift) belongs to the one to whom it was given; it belongs to him and to his heirs, and is inherited by those among his descendants who inherit from him.'"
أَخْبَرَنَا عِيسَى بْنُ مُسَاوِرٍ، قَالَ حَدَّثَنَا الْوَلِيدُ، قَالَ حَدَّثَنَا أَبُو عَمْرٍو، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْعُمْرَى لِمَنْ أُعْمِرَهَا هِيَ لَهُ وَلِعَقِبِهِ يَرِثُهَا مَنْ يَرِثُهُ مِنْ عَقِبِهِ " .
