Bal huwa ayatun bayyinatun fee sudoori allatheena ootoo alAAilma wama yajhadu bi-ayatina (surah Ankabut: 49)

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

(29:49) But it is a set of Clear Signs in the hearts of those who have been endowed with knowledge. *89 None except the utterly unjust will deny Our Signs.

Bal huwa aayaatum baiyinaatun fee sudooril lazeena ootul `ilm; wa maa yajhadu bi aayaatinaa illaz zaalimoon

*89) That is, "The presentation of a Book like the Qur'an by an unlettered person, and the manifestation by him, all of a sudden, of extraordinary qualities of character while nobody ever noticed him making any preparation for these previously, are in fact the clearest Signs which serve as pointers to his Prophethood for those who are possessed of knowledge and wisdom. " If one reviews the life-story of any great historical personage, one can always discover the factors in his environment, which moulded his personality and prepared him for the excellences and qualities that emanated from him in life. There always exists a clear relationship between his environment and the component aspects of his personality. But no source whatever can be discovered in his environment of the wonderful qualities and excellences that the Holy Prophet Muhammad (may Allah's peace be upon him) displayed. In his case, neither in the contemporary Arab society nor in the society of the neighbouring countries with which Arabia had any relations can one discover those factors which could have any remote relationship with the component aspects of the Holy Prophet's personality. This is the reality on whose basis it has been asserted here that the Holy Prophet Muhammad's personality is not one Sign but a collection of many clear Signs. An ignorant person may not see any of these Signs but those who are possessed of knowledge have become convinced in their hearts by seeing these Signs that he is most certainly a true Prophet of Allah.
