КОРАН (английский перевод) - 48.26

And when the unbelievers established in their hearts fierce bigotry, the fierce bigotry of ignorance, Allah sent down His tranquility on His Messenger and the believers and firmly fastened to them the Word of 'taqwa' (there is no god except Allah, and Muhammad is His Messenger, as it is the cause of righteousness) to which they have better right and are worthy of it. Allah has knowledge of all things.
