← Previous Hadith The life-tenancy which the Messenger of Allah (ﷺ) allowed was only that one should say: It is for you and your descendants. When he says: It is yours as long as you live, it returns to its owner.

He then said: I gave a sadaqah (charity to her. He replied: It is more unexpected from you.
