1. In most Islamic States where the Almajir originated from, the western education is intermeshed with the Islamic education, thus learning hours for the Muslims students or pupils is intermission into two phases, that is the western education thoughts and the Islamic education thoughts.
2. But in the African States who merely copied the system from the Arab Almajir children were only a street beggar, who begged for food to cater for both himself and his teacher.

Also:
1. In many Islamic state’s including Saudi Arabia, public school’s both Islamic and western education is free from kindergarten to high school grades.
2. Whereas in Africa, the Almajir children who couldn't afford to acquire western education but are interested in learning must pay tuition fees and subsequent fees before they can gain even Islamic knowledge.

In Africa people believed that since Islam permits polygamy and the proliferation of offspring, the dilapidated AL muhajir system became an institution whereby those who do not have enough saw the institution as the ideal place to proliferate exorbitantly as they wish, for they do not have to cater for what they bring forth to the world.
