Assalamu Aleikum,
I'd like to ask what our prophet meant when he said, "There are 500 years of distance between each heaven." I mean, is this '500 years' by walking/marching? I have read some of your fatwas and some tasfers, and it said that 500 years by marching, but I'd like to learn if this is the words of our Prophet or just an interpretation. Can this '500 years' be by riding, at the speed of light, or other kinds of travel? We know for a fact that our universe is so huge, and 500 years of walking is nothing compared to it. Are there other ways to interpret this hadith? Thank you.
Following are some of the traditions taken from as-Suyutis al-Haya as-saniya fi l-haya as-sunniya that mention this
Ibn Rāhūya, in his Musnad, Abū š-Šayh and al-Bazzar, on the basis of a sound chain of transmission that goes back to Abū Darr, report that God's messenger (God's blessing and peace be with him!) presented the following teaching: "The interval between heaven and earth is the distance of 500 years. The diameter of every heaven is also as much as 500 years. And the interval between this heaven and the one that comes after it is also as big as 500 years. Thus up to the seventh heaven, and with the earths it is similar. And the distance between the seventh heaven and the throne corresponds to all that."
Ahmad b. Hanbal (may God be pleased with him!), in his Musnad, Abū Dā'ūd, at-Tirmidī, who declares it to be of good quality, Ibn Māğa, Ibn Abi Aşamm, in his Sunna, Abū Yaʻlā, Ibn Huzayma, at-Tabarānī, al- Hakim, and giving it a sound derivation Abū š-Šayh have the following tradition from al-'Abbas b. "Abd al-Muttalib: "We were with the Prophet (God's blessing and peace be with him!) when he said: 'Do you know what the distance is between heaven and earth?' - We answered: 'God and His messenger know better!' - He said: 'Between them there is a distance of 500 years; and from every heaven to another heaven there is a distance of 500 years. The diameter of every heaven, too, is 500 years. Above the seventh heaven there is a sea between the surface of which and the greatest depth the distance is as big as that between heaven and earth. Then, above that, there are eight mountain goats; from their knees down to their hoofs, the distance equals that between heaven and earth.
