It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "After me you will see preferential treatment (of others over you) and matters that you will disapprove of." We said: Then what do you command us? He (peace and blessings be upon him) said: "Give them their due, and ask Allah for your due."
