It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that one day he was sitting with some of the noble Companions (may Allah be pleased with them) when the Prophet (peace and blessings be upon him) came and said: "O people! Do you not know that I have come to you as the Messenger of Allah?" The people replied: "Why not, we bear witness that you are the Messenger of Allah." The Prophet (peace and blessings be upon him) said: "Do you not know that Allah Almighty has revealed in His Book a command of this nature that whoever obeys me, it is as though he has obeyed Allah?" The people replied: "Why not, we bear witness that whoever obeys you, obeys Allah; your obedience is the obedience of Allah." The Prophet (peace and blessings be upon him) said: "Then it is also a part of Allah's obedience that you obey me, and it is a part of my obedience that you obey your leaders. Obey your leaders; if they pray sitting, then you also pray sitting."
