Sheikh Yûsuf al-Badrî
The verses in question are:
“And (We sent) Lot when he said to his people: What! do you commit an indecency which any one in all the worlds has not done before you? For ye practice your lusts on men in preference to women. You are indeed a people transgressing beyond bounds.” [Sûrah al-A`râf: 80-81]
Perhaps, the commentator of this verse, wanting to show the seriousness of this sin, interpreted this verse to mean that even animals would not commit such a thing. This may have been his way of trying to convince his audience how reprehensible such an act is.
However, to use these verses as evidence that homosexual behavior is never exhibited by animals is stretching the meaning of these verses a bit too far.
We must keep in mind that Allah does not hold anyone legally accountable for their doings except human beings and the Jinn.
The word in the verse translated as “all the worlds” is the word (`âlamîn). This word is used in this context in reference to humanity and the Jinn (also referred to as al-thaqalayn). Animals are not understood from this word when used in this context.
And Allah knows best.
