Write A speech on the topic 'Prophet Muhammed is my inspirational leader' PLS write as it is for my school

GOOD MORNING!!

YOUR NAME:_______

YOUR INTRODUCTION:_______

The Leadership of Muhammad is a new book by British management scholar John Adair that mines the life of the Prophet Muhammad to highlight his extraordinary qualities as a leader.

According to Adair, success is a function of leadership, and his short work provides anyone interested in learning how to lead and motivate with a wealth of insight, according to this review by Muqtedar Khan, an associate professor of political science and international relations at the University of Delaware.

Over the years, Muslim and non-Muslim historians have written many books about Prophet Muhammad as a leader, highlighting the divinely guided qualities of his personality as the final messenger of God, according to Islamic beliefs. But in the past century or so, a modernist, rationalist school of Islamic thought has emerged, which focuses on examining Prophet Muhammad as a charismatic leader as well as being the messenger of God.

I really don't know how you are going to say.
