Freedom from oppression
This is the Prophet (Sallallahu alaihi wa sallam) who is to free humankind from the clutches of oppression. He is the One to free human intellect from prejudice and favoritism. He is the One who will give their mutual relations an international character. This Hadith of Sunan Abu Dawood is proof enough:
Translation: Beware! If any person oppresses a non-Muslim (with whom there was a prior agreement) and snatches his (or her) right or taxes him beyond his capacity or takes away something without his express wish, then on the Day of Judgment, I will present the case against the aggressor. (Sunan Abu Dawood, Hadith No. 3054)
What a beautiful system did the Holy Prophet (Sallallahu alaihi wa sallam) give us! Even a non-Muslim can’t be oppressed. This is that great aspect of an Islamic system that if someone looks at it with an unprejudiced eye, he/she will surely accept it.
