It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) forbade the sale or gift of wala’.

Imam Malik, may Allah have mercy on him, said that if a slave makes a contract of manumission with his master on the condition that his wala’ (right of inheritance/loyalty) will go to whomever he wishes, then this is not permissible because wala’ will go only to the one who sets him free. And if the master gives the slave permission to make a contract of wala’ with whomever he wishes, even then it will not be permissible, because the Messenger of Allah, peace and blessings be upon him, said:“Wala’ will go to the one who sets free.”And the Messenger of Allah, peace and blessings be upon him, forbade the sale and gift of wala’. So if it were permissible for the master to stipulate the condition of wala’ with the slave or to give him permission to give wala’ to whomever he wishes, then in that case wala’ would become a gift.
