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.)
