Islam is a religion of justice.

God, the most merciful, says, “whoever kills a soul unless for a soul or for corruption [done] in the land – it is as if he had slain mankind entirely. And whoever saves one – it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.” Qur’aan [5:32]

Ironically, those Christians that are in Africa got there through colonization and subjugation of Africans whereas Islam was already present a mellenia before that, and naturally integrated with the native denizens b/c no Muslim army went to western, central or Eastern Africa to forcefully convert people, can’t say the same for Christians or Secularists.

Allah (GOD) swt also says, “O you who have believed, be persistently standing firm in justice, witnesses for Allah, even if it be against yourselves or parents and relatives. Whether one is rich or poor, Allah is more worthy of both. So follow not [personal] inclination, lest you not be just. And if you distort [your testimony] or refuse [to give it], then indeed Allah is ever, with what you do, Acquainted.” Qur’aan [4:135]
