Undoubtedly humankind is in debt to the Holy Prophet as if it wasn’t for him the world would have ceased to exist. Allah gave him the title of ‘the Prophet of Mercy’. So merciful was he that he happily bore the hardships while praying for the people. He never mistreated anyone even though he was troubled the most amongst all the prophets.
He strived for the upliftment of individuals as well as societies, fought the injustices and oppression against women and children, denounced aristocratic privileges, and mandated rulings that led to the freedom of slaves. He taught people to adhere to justice even if it's at the expense of personal interest, to look after the poor and the needy, to take care, love, and respect human beings irrespective of their religion, caste, social status, etc.
The prophet was a person of high morals. Even before the proclaiming of his prophethood people knew him as a truthful and trustworthy person. It is not an exaggeration to say that people were initially attracted to the prophet for his morals than his message as they saw the practical manifestation of the message in him.
None was like him. Even Imam Ali (peace be upon him), whose virtues are incomparable with the rest used to say that I am trained and schooled by the prophet himself. What can be said of the virtues of the teacher whose student goes on to become Ali ibn Abi Talib (peace be upon them)?
Alas! the society of the time was not prepared to benefit from the divine rays and poisoned the one who gave them light. Mankind never saw and nor will see any of his kind, a prophet who tried his best and prayed for the betterment of humanity and rightly known as the ‘Prophet of Mercy’.
On this day we ask Allah to hasten the reappearance of our Imam and to grant us the intercession of our Prophet (peace be upon him and his pure progeny)
