SHAFAQNA – The Prophet Moses (AS) said to Allah (SWT): O’ God, show me the rank and the positions of the Prophet Mohammad (PBUH) and his Ummah. Allah (SWT) replied: O’ Moses (AS) you cannot bear to see it. But for only one time I will show you their positions; and for the sake of that position, I have made superior his (the Prophet of Islam (PBUH)) position to you and all other created beings. Then the kingdom of heavens opened, Moses (AS) looked, due to intensity of lights and the closeness of their positions to God, Moses (AS) nearly died.
Moses (AS) asked God: For what reason, you have given him (the Prophet of Islam (PBUH)) such a great position? Allah (SWT) replied: For the sake of the special creation which I have made exclusive to him. And that is the characteristic of sacrifice (Ithaar). O’ Moses (AS), when those who have sacrificed at one time (in the way of God) come to Me, I am reluctant to pass them through Divine Assessment, and will place them anywhere in the paradise they wishes .
