"Has there not reached you the news of those before you - the people of Noah and ‘Aad and Thamūd and those after them? No one knows them [i.e., their number] but God. Their messengers brought them clear proofs, but they re- turned their hands to their mouths and said, “Indeed, we disbelieve in that with which you have been sent, and in- deed we are, about that to which you invite us, in disquieting doubt.”"— Sahih Intl
