Sunan Abi Dawud, 3560

Mujahid said:'Umra' means that a man says to another man: It belongs to you so long as you live. When he says that, it belongs to him and to his heirs. Ruqba means that a man says to another: From me and from you

Mujahid a dit : « ‘Umra’ signifie qu’un homme dit à un autre : “C’est à toi tant que tu vivras.” Quand il dit cela, cela appartient à lui et à ses héritiers. ‘Ruqba’ signifie qu’un homme dit à un autre : “De ma part et de la tienne.” »
