It is obligatory on Muslims to surrender to and obey the Orders of Allah and those of His Messenger (peace be upon him), and to offer advice sincerely to Allah's Servants for the Sake of Allah. This will definitely bring happiness to all Muslims in this world and the Hereafter and their glory will not be achieved without doing so, as Allah will raise their words high and grant them victory over their enemies, no matter how many and supportive to one another they are.
