Hadith 193

Bulugh al-Maram

Book 7: Business Transactions
وَفِي لَفْظٍ : { إِنَّمَا اَلْعُمْرَى اَلَّتِي أَجَازَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-أَنْ يَقُولَ: هِيَ لَكَ وَلِعَقِبِكَ، فَأَمَّا إِذَا قَالَ: هِيَ لَكَ مَا عِشْتَ، فَإِنَّهَا تَرْجِعُ إِلَى صَاحِبِهَا } 1‏ .‏
A narration has:

"The life-tenancy which Allah's Messenger (ﷺ) allowed was only that in which one says, 'It is for you and your descendants.' However, if he says, 'It is yours as long as you live', it returns to its owner."
