A person could adapt his living from the working hours of the Imam. The household of the Imam understood his living routine like a mechanical timepiece and thus they would adjust their programs on the basis of the Imam's routine. They know exactly what time the Imam sleeps; what time he awakens; when he must take tea and what time he would come out for appointments.[1]
