Rasoolun mina Allahi yatloo suhufan mutahhara (surah Bayyinah: 2)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(98:2) a Messenger *4 from Allah, reciting from Purified Scrolls; *5

Rasoolum minal laahi yatlu suhufam mutahharah

*4) Here, the Holy Prophet (upon whom be peace) himself has been called "the clear evidence", for his life before and after Prophethood, his presenting a Book like the Qur'an in spite of being .un-lettered, his bringing about an extraordinary revolution in the lives of the converts to Islam through education and training, his educating the people in rational beliefs, clean and pure forms of worship, excellent morals and the best principles and ,injunctions for human life, perfect harmony and agreement between his word and deed, and his constancy of purpose in respect of his message in spite of every kind of resistance and opposition, all these were clear signs of the truth that he was Allah's Messenger.
*5) Lexically, suhuf means "written pages", but in the Holy Qur'an this word has been used as a term for the Books revealed to the Prophets of Allah (peace be upon them); and by the holy scriptures are meant the scriptures which are free from every mixture of falsehood, every kind of error and moral filth. The full import of these worde becomes evident when one studies the Bible (and the books of other religions as well) vis-a-vis the Holy Qur'an, and finds written in them along with sound teachings such things as are not only opposed to truth and reason but are also morally contemptible. After reading them when one turns to the Qur'an, one realizes how pure and hallowed this Book is.
