Shaikh Rabee Bin Haadi Al-Madkhali (may Allaah preserve him) stated after defining what oppression (or injustice) is:
Indeed, it is clear to you that Dhulm (oppression or injustice) is to put something in other than its (rightful) place. Therefore, the one who rebuts a Mubtadi (an innovator) or a book in which there is Bidah, or disparages one who is deserving of disparagement, or rebukes one who deserves to be rebuked, (such as) some narrator, false witnesser and a sinner who announces his sin, then he (i.e. this refuter, rebuker) is not an oppressor because he has put the affairs in their proper and (rightful) places, and the oppressive transgressor is the one who embarks upon speaking ill of him and conspires against him. In reality, he (i.e. the one who speaks ill of this upright refuter, rebuker) is the one who puts something in order than its (rightful) place due to the fact that he praises the criminals- the callers to the gates of the hell fire- and speaks ill of those who give sincere advice to the Muslims.
Whoever defends them (i.e. the innovators) and argues on their behalf with falsehood, then he is from those more deserving of the statement of Allaah:
وَلَا تُجَـٰدِلۡ عَنِ ٱلَّذِينَ يَخۡتَانُونَ أَنفُسَہُمۡۚ إِنَّ ٱللَّهَ لَا يُحِبُّ مَن كَانَ خَوَّانًا أَثِيمً۬ا
يَسۡتَخۡفُونَ مِنَ ٱلنَّاسِ وَلَا يَسۡتَخۡفُونَ مِنَ ٱللَّهِ وَهُوَ مَعَهُمۡ إِذۡ يُبَيِّتُونَ مَا لَا يَرۡضَىٰ مِنَ ٱلۡقَوۡلِۚ وَكَانَ ٱللَّهُ بِمَا يَعۡمَلُونَ مُحِيطًا
هَـٰٓأَنتُمۡ هَـٰٓؤُلَآءِ جَـٰدَلۡتُمۡ عَنۡہُمۡ فِى ٱلۡحَيَوٰةِ ٱلدُّنۡيَا فَمَن يُجَـٰدِلُ ٱللَّهَ عَنۡہُمۡ يَوۡمَ ٱلۡقِيَـٰمَةِ أَم مَّن يَكُونُ عَلَيۡہِمۡ وَڪِيلاً۬
And argue not on behalf of those who deceive themselves. Verily, Allah does not like anyone who is a betrayer of his trust, and indulges in crime. They may hide (their crimes) from men, but they cannot hide (them) from Allah, for He is with them (by His Knowledge), when they plot by night in words that He does not approve, and Allah ever encompasses what they do. Lo! You are those who have argued for them in the life of this world, but who will argue for them on the Day of Resurrection against Allah, or who will then be their defender? [4:107-109]
