Surah 11. Hud, Ayah 107

I.e., unless God wills to reprieve them (cf. the last paragraph of 6:128 and the corresponding note [114], as well as note [10] on 40:12 ). The phrase "as long as the heavens and the earth endure" has caused some perplexity to most of the classical commentators in view of the many Qur'anic statements to the effect that the world as we know it will come to an end on the Last Day, which is synonymous with the Day of Resurrection. This difficulty, however, can be resolved if we remember - as Tabari points out in his commentary on the above verse - that in ancient Arabic usage the expressions "as long as the heavens and the earth endure", or "as long as night and day alternate", etc., were used metonymically in the sense of "time beyond count" (abad). See also {20:105-107} and the corresponding note [90], as well as note [63] on 14:48 .

 Sinful believers will eventually be removed from Hell after receiving their punishment.

Khalidin: This is the word which is usually translated "dwell for ever" or "dwell for aye". Here it is definitely connected with two conditions, viz: (1) as long as the heavens and the earth endure, and (2) except as Allah wills. Some Muslim theologians deduce from this the conclusion that the penalties referred to are not eternal, because the heavens and the earth as we see them are not eternal, and the punishments for the deeds of a life that will end should not be such as will never end. The majority of Muslim theologians reject this view. They hold that the heavens and the earth here referred to are not those we see now, but others that will be eternal. They agree that Allah's Will is unlimited in scope and power, but that It has willed that the rewards and punishments of the Day of Judgment will be eternal.
