عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا قَالَ إِنَّمَا الْعُمْرَى الَّتِي أَجَازَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ يَقُولَ هِيَ لَكَ وَلِعَقِبِكَ فَأَمَّا إِذَا قَالَ فَهِيَ لَكَ فَإِنَّمَا تَرْجِعُ إِلَى صَاحِبِهَا
Narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them), he says: The Umra (gift for life) which the Messenger of Allah (peace and blessings of Allah be upon him) enforced, its form is that the giver says: "This thing is for you and for your heirs." When he only says: "This thing is for you," then that thing will return to the original owner.
