Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that the Holy Prophet (peace and blessings be upon him) forbade ruqba and said: Whoever receives a house as ruqba, it belongs to him. (Ruqba is when a person says to another: I have gifted you this house; if you die before me, it will return to me, and if I die before you, it will be yours.)

The Noble Prophet (peace and blessings be upon him) said: Raqbah is not permissible. Whoever receives a house through raqbah, it will be divided as inheritance.

The Noble Prophet (peace and blessings be upon him) said: "Ruqba has no validity. Whoever receives a house as ruqba, it will belong to the heirs of the giver."

Hazrat Ali (may Allah be pleased with him) said: The ruling of 'Umra and Ruqba is the same.

Hazrat Mujahid (may Allah have mercy on him) said: Whoever receives a house as 'Umri', it will belong to him during his lifetime, and after his death, it will go to his heirs. Such a house will not return to the one who gave it as 'Umri', and 'Ruqba' is also similar to this. I asked Mujahid (may Allah have mercy on him) what is the meaning of 'Ruqba'? He replied: 'Ruqba' is when a person says that this house will belong to whichever of us lives longer.

Hazrat Ibn Abbas (may Allah be pleased with both of them) states that 'Umra and Ruqba are equal. Hazrat Waki' says that when possession is taken of 'Umra, gift, grant, and loan, it becomes effective.
