This great change in their thought and action was the result of their true faith in Allah. In addition to this, their faith opened the door of knowledge and wisdom upon them which is manifest from their invocation to Allah at this occasion. They prayed, رَبَّنَا أَفْرِغْ عَلَيْنَا صَبْرًا وَتَوَفَّنَا مُسْلِمِين '` O Allah! Shower upon us patience and let death take us while we are Muslims." This prayer is not only a manifestation of knowledge and wisdom, but also the best means of getting out of the difficulty they were in. It is because perseverance and patience are the only keys to success over one's enemy.
The report of the commission formed for investigating the causes and effects of the World War has remarked that the Muslims who observe faith in Allah and in the Hereafter are the most valiant and brave people in the battle field, and the most patient in the times of difficulty because they have faith in Allah and in the Hereafter. This is why the German military officials, expert in military sciences, emphatically suggested that they should create honesty and sense of accountability in the Hereafter among their soldiers, as they are the great source of strength and courage.

It was A Miracle
The instant perfect change of mind of the sorcerers was, in no way, a lesser miracle than the other miracles of the prophet Musa (علیہ السلام) . Those who led a life of infidelity and ignorance for their whole life were instantly changed into the most cognizant, knowledgeable and true Muslims, as faithful as to readily sacrifice their life for their faith. It is a pity that the Muslims and the Muslim states are trying all other ways and means to make themselves powerful and strong, but have become neglectful of the real source of power and strength. That is faith, perseverance and patience.
