'O Bilāl, call the Iqāmah for the prayer; give us comfort by it.'

A man from the Companions said: I wish I had prayed and got comfort. Those around him seemed to disapprove of his statement. So, he said: I heard the Prophet (may Allah's peace and blessings be upon him) say: O Bilāl, make the call to prayer and proclaim its commencement so that we will get comfort by it. This is because it includes private communication with Allah Almighty and provides relief for the soul and the heart.
