Indeed, it is We who sent down the Qur'an and indeed, We meaning

*6) That is, "You should note it well that it is We Who have sent this `Word'. Thus it is not Our Messenger whom you are calling `insane' but in fact this abusive remark applies to Us. Moreover, you should know that it is Our 'Word' and We are preserving it; therefore, you can do no harm to it; nor can you discredit it by your ridicules, taunts and objections: nor can you hamper its progress, whatever you may do against it: nor will anyone be ever able to change or tamper with it. "
