Like all other prophets assigned to guide the human being, Muhammed used a strongly eﬀectve, reasonable and moderate style of speech both in his relatonships with people and in his mission of advice. He always considered the positon, situaton and psychology of his audience during his speech. Since he had an advice-andeducaton-focused mission, he paid much atenton to be gracious, sof and modest when he talked. He avoided not only extravagance and understatement but also empty and needless talk. In every circumstance, his style of speech and propriety took place under a divine supervision.
