Emperors and Kings acting like gods, enslaving and exploiting the innocent, sporting events where peoples cheered killings, wars, bizarre and harmful medical practices, superstitions, self torture or tourturing other peoples in the name of religion, slavery, non existent rights to fundemental needs and a soceity of uncertainity for the poor, week and innocent and a society where the value of life was determined by the wealth they held, prosecution of critical thinkers, and prosecution of peoples who tried to stand up for human rights. That was the world before the Holy Prophet s.a.w.

Holy Prophet s.a.w brought the mercy and light of good charecter to the world filled with the darkness of tryanny, barbarism and superstitions. Even before the decleration of prophethood, the peoles used to call him "Sadiq" (truthful) and "Ameen" (honest). He advocated for the fundamental rights for everyone, opposed tyranny and opression and stood up for the rights of the poor and helpless innocents.
So, the earliest people who accepted Islam were poors, orphans and widows. While the first ones to oppose him were the tyrants of that time. That explains a lot.
In later articles, I will explain how He s.a.w and his inheritors, who implemented his teachings of peace, love and equality, have brought change globally.
