“Muhammad did not bargain and did not accept the bargaining for one moment in the subject of his message on the many arts of bargaining and the intensification of adversity, he says ‘if they put the sun on my right and the moon in my left to leave this matter, I would never leave it’ A firm belief, and immeasurably steadfastness, and a legacy that left the Arabs indebted to Muhammad bin Abdullah, who left them a nation of great significance under the sun in human history”
