Imam Nawawi (Mercy of ALLAAH be on him) has written in his Tahzib that ALLAAH (the Most High) had assembled all the excellences and virtues of characters and habits in the person of the Holy Prophet (Sallallahu Alaihi Wa Sallam). ALLAAH (the Most High) had endowed him with all the knowledge of the ancient and later peoples, even though he was unlettered – being unable to read and write – and had no human teacher; yet he had been endowed with such knowledge as Allah (the Most High) had not bestowed on anyone else. Prophet Muhammad (Sallallahu Alaihi Wa Sallam) was offered keys to the mundane treasures but he preferred the Hereafter to the worldly riches.
Hadrat Anas (Radi Allaahu Ta’ala Anhu) has narrated that the Holy Prophet (Sallallahu Alaihi Wa Sallam) was the greatest possessor of knowledge and wisdom. He was the most honourable, just, human and forbearing, virtuous and chaste, beneficent, patient and fortitudious of all men (Wasa’il-ul-Wasulila-Sham’il-ir-Rasul). Bukhari and Muslim have related on the authority of Hadrat Anas (Radi Allaahu Ta’ala Anhu) that the Holy Prophet (Sallallahu Alaihi Wa Sallam) was more handsome, courageous and generous than anyone else because he was the noblest of all men, and he was the most even-tempered. Definitely, the acts and deeds of one possessing these merits will be model of the best deeds, he will be possessing the comeliest face and his character will be of the highest standard. The Holy Prophet (Sallallahu Alaihi Wa Sallam) was therefore, the agglomeration of all the qualities of bodily and spiritual perfection.
May ALLAAH bless him infinitely.
