It is narrated from Sa'id bin Abi Sa'id (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) said: "On the Day of Resurrection the Noble Qur'an will come in the most beautiful state and the finest appearance, and will say: 'O my Lord! You have given every doer the reward of his deed, so where is the reward for my deed?' So the companion of the Qur'an will be clothed in a garment (of honour) and crowned with the crown of sovereignty. Then the Qur'an will say: 'O my Lord! I desired for him something even greater than this.' So eternity will be given to him in his right hand and blessings in his left. Then he will be asked: 'Are you pleased?' He will say: 'Yes, O my Lord! (I am pleased.)'"
