كتاب الهبات
(3) Chapter: Lifelong Grant
(3.00) باب الْعُمْرَى
Sunan Ibn Majah 2380 
It was narrated that Jabir said:
“I heard the Messenger of Allah (ﷺ) say: 'Whoever gives a lifelong grant to a man, it belongs to him (the recipient) and to his heirs. His (the giver's) words put an end to his right to it, and it belongs to the one to whom it was given for life and to his heirs.”
حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، عَنْ جَابِرٍ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏ "‏ مَنْ أَعْمَرَ رَجُلاً عُمْرَى لَهُ وَلِعَقِبِهِ فَقَدْ قَطَعَ قَوْلُهُ حَقَّهُ فِيهَا فَهِيَ لِمَنْ أُعْمِرَ وَلِعَقِبِهِ ‏"‏ ‏.‏
