It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Soon after me, you will see favoritism and matters that you will dislike." The noble companions (may Allah be pleased with them all) asked: "O Messenger of Allah (peace and blessings be upon him)! What should the one among us who encounters that time do?" He said: "Fulfill the duties that are obligatory upon you and ask Allah for your rights."
