Surah 17. Al-Israa, Ayah 49

They do not realise that Allah Who created them once out of nothing can create them again, with memories of their past, in order to render to Him an account of how they used or misused the talents and opportunities which they were given. If it is to be a new Creation, what then? Bones and dust or ashes may yet retain something of the personality which was enshrined in them. But even if they were reduced to stones or iron or anything which their minds can conceive of as being most unlike them, yet there is nothing impossible to Allah! He has clearly sent a Message that we shall have to render an account of ourselves, and His Message is necessarily true.
