Dr Hassan Mohi-ud-Din Qadri said that fasting is that form of worship whose reward Allah Almighty has promised Himself. He said that fasting imparts a lesson of patience, patience that endows on man spiritual and moral excellence. He said that rewards of worship done during the sacred moments in the holy month of Ramazan increase manifold, so much so that blessings bestowed on the believers cannot be counted.
