(This is the Scripture), i.e. this is the Book that Muhammad (pbuh) is reciting to you; (whereof there is no doubt). There is no doubt that it has come from Me; if you believe in it, I shall guide you, but if you do not believe in it, I will torment you. It is also said that (This is the Scripture) refers to the Guarded Tablet. It is also said that this means: This is the Book that I promised to reveal to you on the Day of the Covenant (yawm al-mithaq). It is also said (this is the Scripture whereof there is no doubt) means there is no doubt that the description and traits of Muhammad are found in the Torah and Gospel. (A guidance unto those who ward off (evil)), means that the Qur'an is an exposition for those who ward off disbelief, associating partners with Allah and indecencies. It is also said that it means: it is a favour to the believers; or that it means it is a mercy unto those who ward off evil from among the community of Muhammad (pbuh).
