I think they are wrong to do it.
Evolution does not say there is no God. Evolution cannot say there is no God. Evolution has nothing to do with the existence of God. Evolution is about how life changes, not God.
I believe that God exists, and evolution is how life changes to suit its needs.
You could think evolution is the way God creates life; "continual, eternal creation of God". "Evolution is the mechanism of creation".
Or you could think that God "guides" the evolution of species. But I don't think this it is "guided" by God.
Or both.
The Qur'an does say seven seas could not contain all of the words of God.
But Islam does not say that God created life in one day, or say anything against evolution, in my opinion.
I think it is only misconceptions of evolution and from reading the Qur'an without looking deeper into the meanings. The Qur'an says it uses "unspecific" (Arabic: متشابهات
verses too.
Sahih International: It is He who has sent down to you, [O Muhammad], the Book; in it are verses [that are] precise - they are the foundation of the Book - and others unspecific. As for those in whose hearts is deviation [from truth], they will follow that of it which is unspecific, seeking discord and seeking an interpretation [suitable to them]. And no one knows its [true] interpretation except Allah. But those firm in knowledge say, "We believe in it. All [of it] is from our Lord." And no one will be reminded except those of understanding.
