Masha Allah you have expressed the right thoughts about the flag of Pakistan. The flag of Pakistan shows the greatness and strength of the country. You have rightly said that the flag of Pakistan is very important from the point of view of Islam because white and green colors are given great importance in Islam and by using these two colors in the flag it has been represented that Pakistan is a Muslim country and in this country Muslims can live their lives according to Islam. The drawing that your daughter made of flag is really amazing
