The Angel of the Mountains
Another one is the angel entrusted with the mountains. He is mentioned in the hadith when the Prophet, may Allah bless him and grant him peace, went out at night to visit the Banu Abd and returned from them. That hadith contains the statement of Jibril to him:
"Allah has heard what your people said to you and the reply they gave you. He has sent the Angel of the moun- tains with me so that you can command him as you wish. If you wish, he will crush your people by causing the mountains to fall on top of them, or if you wish, he will make the earth swallow them up." The Prophet, may Allah bless him and grant him peace, said, "Give them more time. Hopefully Allah will bring forth from their loins people who will worship Allah without associating anyone else with Him."
The Angels of the Ranks
They include the angels of the ranks who do not slacken in worship, those who stand and do not bow, those who bow, and those who prostrate and do not come up from their prostration. And there are others who are different from any of these:
"None knows the hosts of your Lord except Him. It is nothing but a reminder to all human beings." (74:31)
Imam Ahmad reports in his Musnad, as does at-Tirmidhi, from Abu Dharr, may Allah be pleased with him, that the Messenger of Allah, may Allah bless him and grant him peace, said:
"I see what you do not see and I hear what you do not hear. The heaven groans and it has a right to groan. There is no place in it the size of four fingers which does not
have an angel prostrating in it. If you knew what I knew, you would laugh little and weep much and not enjoy women in your beds and you would go out to the hill cry- ing out to Allah, the Mighty and Majestic."
The meaning of "the heaven groans" is that it makes the sound of the creaking of a saddle which is placed on the camel's back, i.e. due to the great number of the angels in it, which weighs it down so that it groans.
