Is the Rock in
    Bayt al-Maqdis (Jerusalem) suspended in the air?
Question

                They told us that the sacred rock from
      which the Prophet 
 (peace and blessings of Allaah be upon him) started his ascent into
      heaven on the night of the Mi’raaj is suspended in the air by the power of Allaah.
      Please tell us if this is correct, may Allaah reward you.
Praise be to Allah.Everything is standing in its position by the permission of Allaah,
    whether it be the heavens and all that is in them or the earth and all that is on it
    – even the rock which you asked about. Allaah says (interpretation of the meanings):
“Verily, Allaah grasps the heavens and the earth lest they move
    away from their places, and if they were to move away from their places, there is not one
    that could grasp them after Him…” [Faatir 35:41]
“And among His Signs is that the heaven and the earth stand by His
    Command…” [al-Room 30:25]
The Rock in Bayt al-Maqdis is not suspended in space with air around it
    on all sides; it is attached to the side of the mountain of which it is a part and by
    which it is supported; both it and the mountain stand in their positions because of the
    well-known physical laws governing the universe; in this regard it is like everything else
    that exists. We do not deny that Allaah is Able to hold part of His creation in space; all
    of creation is standing in space by the power of Allaah, as stated above. Allaah raised
    the mountain above the people of Moosa when they refused to follow the laws that Moosa
    brought them. It was held up by the power of Allaah. Allaah says (interpretation of the
    meaning):
“And (remember) when We took your Covenant and We raised above
    you the Mount (saying): ‘Hold fast to that which We have given you, and remember that
    which is therein so that you may become al-muttaqoon (the pious).” [al-Baqarah 2:63]
“And (remember) when We raised the mountain over them as if it had
    been a canopy, and they thought that it was going to fall on them. (We said): ‘Hold
    firmly to what We have given you, and remember that which is therein, so that you may fear
    Allaah and obey Him.” [al-A’raaf 7:171]
But our point here is to explain what is in fact the case: the rock in
    Jerusalem is not suspended in space, completely separate from the mountain; it is attached
    to it and is supported by it. And Allaah knows best.
