Praise be to Allah.
Firstly: The matters that you have asked about are matters of the Unseen which man cannot know except via Revelation – i.e., the Qur’aan and Sunnah. Undoubtedly the divine descent ends at the lowest heaven, and Allaah does not descend to the earth, as the Prophet (peace and blessings of Allaah be upon him) stated: “Our Lord descends to the lowest heaven,” he did not say: to the earth.
Secondly: With regard to what you mentioned about Allaah coming in the shade of the clouds, and that some animals recognize that, after researching in the available books of hadeeth, and studying the words of the scholars of deep knowledge who spoke of the issue of the descent of the Lord – may He be exalted – to the lowest heaven, we did not find anything to indicate that any such thing can be proven. What we have to do is to affirm that which was affirmed by the Messenger of Allaah (peace and blessings of Allaah be upon him), which is that Allaah descends to the lowest heaven, and that He descends in a manner that befits Him, and we refer knowledge of anything other than that to the One Who knows it, may He be exalted and glorified, for He is the All-Knowing, All-Wise.
But it states in the Holy Qur’aan that when Allaah comes on the Day of Resurrection to pass judgement, He will come in the shade of the clouds, as Allaah says (interpretation of the meaning):
“Do they then wait for anything other than that Allaah should come to them in the shadows of the clouds and the angels? (Then) the case would be already judged. And to Allaah return all matters (for decision)”
But this will happen on the Day of Resurrection.
And it should be noted that there is no contradiction at all between our belief that Allaah is above all things and that He is the Exalted, the Almighty, and our belief that He descends to the lowest heaven, for the highness of Allaah is one of His essential attributes which cannot alter or change – i.e., it cannot be other than it is described at any time – so there is no contradiction between them, firstly, because the texts refer to both of them (i.e., His descending and His highness), and the texts cannot say anything that is impossible as is well known; and secondly, because there is nothing like unto Allaah in all His attributes, so His descending is not like the descening of any of His creatures so that one could say that it contradicts the idea of His being exalted.
And Allaah knows best.
