But Jesus ascended to heaven in both soul and body, and the same has been said of Idrīs. Abraham, Moses, and the others, however, are buried in the earth. The Messiah—may Allah’s peace and blessings be upon him and all the other prophets—will certainly descend to earth at the white minaret east of Damascus. He will kill the False Messiah, break the cross, and kill swine, as established in authentic hadiths. This is why he was in the second heaven, although he is superior to Joseph, Idrīs, and Aaron: unlike the others, he intends to descend to earth before the Day of Resurrection.
Adam was in the lowest heaven because the souls of his descendants are presented to him: the souls of the blessed (whereas the gates of heaven will not be opened to the wretched, nor will they enter Paradise until a camel passes through the eye of a needle). He must therefore be close to them when they are presented to him.
As for the Prophet’s seeing Moses standing in prayer in his grave and also seeing him in heaven, there is no contradiction between the two. Souls are like angels in this respect: in a single instant, they ascend and descend as an angel does; they are not like the body in this regard. Elsewhere, I have discussed at length the states of souls after their separation from their bodies, mentioning some of the hadiths, transmitted reports, and evidence concerning this.
