The sixth is the keeper of Paradise. Some reports mention that his name is Riḍwān, and he has been placed in charge of the Garden just as Mālik has been placed in charge of the Fire. For every angel whose name is known to us we affirm faith in him by name; as for those whose names we do not know, we affirm faith in them in general—believing in the tasks we have been told they perform, in the qualities described for them, and in everything the Book and the Sunnah have related concerning the attributes of these angels.
Question: We have said that the angels are part of the unseen realm; can they nevertheless be seen? The answer is: yes, they can—either in the form in which they were created or in another form Allah chooses for them. Thus, on the Day of Badr He said to them: “I am with you, so make firm those who believe; I will cast terror into the hearts of those who disbelieve—strike above their necks and strike every fingertip of theirs” (al-Anfal 8:12). At such moments they may appear in their own form.
Gabriel, for instance, was seen by the Prophet—may Allah bless him and grant him peace—in his original form on two occasions: once on earth, at the mouth of Ḥirāʾ near Mecca, and once in heaven, by the Lote-Tree of the Ultimate Boundary, as Allah says: “And indeed he saw him on another descent, by the Lote-Tree of the Furthest Boundary” (al-Najm 53:13–14). The Prophet saw him with six hundred wings that filled the entire horizon. Only Allah knows the true extent of those wings; but when something lofty fills the horizon, that simply means it is immeasurably vast.
These were the two times the Prophet saw Gabriel in his true form. On other occasions Gabriel would come to him in the likeness of a human being, as in the ḥadīth narrated by ʿUmar, where he appeared as a man with intensely black hair and exceedingly white garments, bearing no trace of travel, and whom none of the Companions recognized. Allah is capable of all things, and He has granted the angels the ability to assume human shapes—whether by their own choice or by His—
