Praise be to Allah.
Firstly, we have to know the ‘aqeedah (belief) of Ahl al-Sunnah wa’l-Jamaa’ah concerning the names and attributes of Allaah. The belief of Ahl al-Sunnah wa’l-Jamaa’ah is to affirm the names and attributes which Allaah has affirmed for Himself, without distorting or denying them, discussing how they are or likening them to anything else. They believe that which Allaah has commanded them to believe, for Allaah says (interpretation of the meaning):
“There is nothing like Him, and He is the All Hearer, the All Seer”
Allaah has told us about Himself. He says (interpretation of the meaning):
“Indeed, your Lord is Allaah, Who created the heavens and the earth in Six Days, and then He rose over (Istawaa) the Throne (really in a manner that suits His Majesty).
“The Most Gracious (Allaah) rose over (Istawaa) the (Mighty) Throne (in a manner that suits His Majesty).
and there are other aayahs which mention that Allaah rose over His Throne.
The rising of Allaah over His Throne, which means that He Himself is High and above the Throne, is of a special nature which befits His Majesty and Might. No one knows how it is except Him.
This was proven in the saheeh Sunnah, where it is narrated from the
(peace and blessings of Allaah be upon him) that Allaah descends during
the last third of the night. It was narrated from Abu Hurayrah that
(peace and blessings of Allaah be upon him) said: “Our Lord descends
every night to the lowest heaven when the last third of the night remains,
and He says, ‘Who will call Me that I might answer him, who will ask
of Me that I might give him, who will ask My forgiveness, that I might
forgive him?’” (narrated by al-Bukhaari, Kitaab al-Tawheed, 6940;
Muslim, Salaat al-Musaafireen, 1262)
According to Ahl al-Sunnah, the meaning of this descent is that Allaah Himself comes down to the lowest heaven in a real sense, as befits His Majesty, and no one knows how that is except Him.
But does the fact that Allaah comes down mean that He vacates the Throne or not? Shaykh Ibn ‘Uthaymeen said concerning a similar question: we say that this question is based on unnecessary and excessive questioning, and that the one who asked this is not to be thanked for his question. We ask, are you more keen than the Sahaabah to understand the attributes of Allaah? If he says yes, we tell him, you are lying. And if he says no, we tell him, then be content with what they were content with. They did not ask the Messenger of Allaah (peace and blessings of Allaah be upon him), ‘O Messenger of Allaah, when He comes down, does He vacate the Throne?’ Why do you need to ask this question? Just say, He comes down. Whether or not the Throne is vacated is not your business. You are commanded to believe the reports, especially concerning the essence of Allaah and His attributes, for this matter is above rational thought.
Majmoo’ Fataawa Shaykh Muhammad al-‘Uthaymeen, 1/204-205
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said concerning this matter:
“The correct view is that He descends and that He does not vacate the Throne. A person's soul remains attached to his body night and day until he dies, but when he is asleep it ascends… It was said, night varies, and the last third of the night comes sooner in the east than in the west, so the descent of Allaah to the lowest heaven, of which His Messenger spoke, happens in the east first and then in the west...”
See Majmoo’ Fataawa Ibn Taymiyah, 5/132
Rising over (istiwaa’) and descending are two of the practical attributes which have to do with the will of Allaah. Ahl al-Sunnah wa’l-Jamaa’ah believe in that, but in this belief they avoid likening Allaah to any of His creation or discussing how He is. It cannot occur to them that Allaah’s descending is like the descending of any of His creatures or that His rising over the Throne is like the rising over of any of His creatures, because they believe that there is nothing like unto Allaah and He is the All-Hearer, All-Seer. They know on rational grounds that there is a great difference between the Creator and His creatures, in their essence, attributes and actions. It cannot occur to them to ask how He descends, or how He rose over His Throne. The point is that they do not ask how His attributes are; they believe that there is a ‘how’, but it is unknown, so we can never imagine how it is.
We know for certain that what is narrated in the Book of Allaah or the Sunnah of His Prophet (peace and blessings of Allaah be upon him) is true and is not self-contradictory, because Allaah says (interpretation of the meaning):
“Do they not then consider the Qur’aan carefully? Had it been from other than Allaah, they would surely, have found therein many a contradiction”
because contradictions in the reports would mean that some of them were showing others to be false, and this is impossible in the case of that which Allaah and His Messenger tell us.
Whoever imagines that there are any contradictions in the Book of Allaah or the Sunnah of His Messenger (peace and blessings of Allaah be upon him), or between the two, it is either because of his lack of knowledge or because he has failed to understand properly or to ponder the matter correctly, so let him seek further knowledge and strive to think harder until the truth becomes clear to him. Then if the matter is still not clear to him, let him leave it to the One Who is All-Knowing and let him put a stop to his illusions and say, as those who are firmly grounded in knowledge say, “We believe in it; the whole of it (clear and unclear Verses) are from our Lord” [Aal ‘Imraan 3:7 – interpretation of the meaning]. Let him know that there is no contradiction in the Qur’aan and Sunnah and no conflict between them. And Allaah knows best.
See Fataawa Ibn ‘Uthaymeen, 3/237-238
Imagining that there is a conflict between Allaah’s descending to the lowest heaven and His having risen over the Throne and His being high above the heavens stems from making a comparison between the Creator and the created being. For man cannot imagine the unseen things of His creation, such as the delights of Paradise, so how can he imagine the Creator, may He be glorified and exalted, the Knower of the Unseen. So we believe in what has been narrated of His rising over (the Throne), His descending and His being High and Exalted. We affirm that (and state that it is) in a manner that befits His Majesty and Might.
