PBUH

Dear Sheikhs! As-Salam `Alaykum! I and every Muslim in this world should feel indebted to our beloved Prophet Muhammad, peace and blessings upon him. Could you please highlight some of the infinite favors of Allah that were showered on the whole human race by the advent of Muhammad? Actually, I know deep in my heart that the Prophet (PBUH) was sent as a savior for mankind, and he was a light shone to rescue the man out of darkness. But I need you good words for my non-Muslim friends!
