Ан-Намль 27:14

Moses had gone to the mountain to obtain a burning brand. But after reaching it, he came to know that he had been called there to have prophethood bestowed upon him. When Almighty God blesses any subject of His with a special gift, He gives it suddenly and unexpectedly, so that the recipient may attribute it directly to God and develop in himself the most profound feelings of gratitude towards Him. On the one hand, the community of Moses (the Children of Israel), though a believing community, had degenerated. On the other, Moses had to proclaim the message of God to a tyrant king like Pharaoh. Therefore, Almighty God blessed him with the miracle of the stick at the very beginning of his mission. This stick was an enduring divine power for Moses, by means of which nine miracles were performed to awe the Pharaoh, apart from the miracles which were meant for the Children of Israel. The miracles of Moses finally established his truthfulness. In spite of this, Pharaoh and his companions did not accept him. The reasons for this were their proneness to transgression, their false pride, and their unwillingness to curtail their freedom. Moreover, they knew that accepting Moses’s preaching would amount to negating their own greatness. And who accepts Truth at the expense of his own greatness?
