Shaykh Ahmad al-Qattaan narrates:
One day we visited the Shaykh whilst he was suffering from an ailment in his leg. The doctor stood beside the Shaykh for an hour seeking the Shaykh’s permission to begin treating him, but the continuous telephone calls from the people seeking religious answers to their questions led to the doctor standing for a long time. Even when we left the Shaykh, the doctor had as yet been unable to treat him.
