The Islam that we know is a faith devoted to the worship of one God, as revealed through The Holy Qu'ran. It teaches the value and importance of charity, mercy, and peace.
"The Best Thing To Give To Your Enemy Is Forgiveness; to An Opponent, Tolerance; To A Friend, Your Heart; to Your Child, A Good Example; To A Father, deference; To Your Mother, Conduct That Will Make her Proud Of You; To Yourself, Respect; To All Others, Charity."
The notion that inspiration is something that happened thousands of years ago, and was then finished and done with. . . the theory that God retired from business at that period and has not been heard from since, is as silly as it is blasphemous.
