Allah and His angels send blessings on the Prophet. O ye who believe! you alsoshould invoke blessings on him and salute him with the salutation of peace. Verily, those who malign Allah and His Messenger — Allah has cursed them in this world and in the Hereafter, and has prepared for them an abasing punishment. [The Holy Quran – 33:57-58]
The Prophet Muhammadsa was the Mohsin-e-Insaaniyyat (Benefactor of Mankind), the Rahmatullil Alameen (Mercy of all Mankind) and the Beloved of God who would stay awake all night in deep anguish that humanity be saved from ruin. He would express such agony and sorrow to alleviate the pains of mankind that the God of the Heavens, addressing the Holy Prophetsa stated, “So haply thou wilt grieve thyself to death for sorrow after them if they believe not in this discourse.”(Holy Quran, Ch.18:V.7)
“The life of the Holy Prophet, peace be on him, was a life of grand success. In his high moral qualities, his spiritual power, his high resolve, the excellence and perfection of his teaching, his perfect example and the acceptance of his prayers, in short, in every aspect of his life, he exhibited such bright signs that even a person of low intelligence, provided he is not inspired by unreasonable rancour and enmity, is forced to confess that he was a perfect example of the manifestation of Divine qualities and was a perfect man.” (The Promised Messiah, Al-Hakam, 10th April, 1902, p. 5)
