The Name of Allah, The Most Merciful, the Bestower of Mercy.

Aisha, may Allah be pleased with her said:

There was no behaviour more hateful to Allāh’s Messenger, peace and blessings of Allah be upon him, than lying. A man would tell a lie when speaking in the presence of the Prophet, and he would not be satisfied until he knew that he had repented from it. [at-Tirmidhi‌ 1973]

Allah, The Most High, said:

وَلَا تَرْكَنُوا إِلَى الَّذِينَ ظَلَمُوا فَتَمَسَّكُمُ النَّارُ وَمَا لَكُم مِّن دُونِ اللَّهِ مِنْ أَوْلِيَاءَ ثُمَّ لَا تُنصَرُونَ

And incline not toward those who do wrong, lest the Fire should touch you, and you have no protectors other than Allah, nor you would then be helped. (Hud: 113)

Al-Allamah Rabee Bin Hadi al-Mad’khali, may Allah have mercy upon him, said:

Do not incline towards the oppressors – those who unjustly harm the people by shedding their blood, seizing their wealth, and violating their honour. They may also oppress the people in matters of religion through bidah, misguidance, and spreading harmful propaganda that contradicts Islam. Avoid associating with any of these individuals; do not support or assist them in their falsehood. The verse covers all categories of oppressors. Every follower of falsehood, every innovator in religious matters, and anyone who dishonours a Muslim is considered an oppressor. Therefore, refrain from aligning yourself with any of them to avoid being affected by the fire of hell. When you incline towards a sinner, an innovator in religious affairs, an oppressor, a criminal, someone who dishonours others, or those who violate the sanctity of the divine legislation, it is as if you are pleased with them, as if you are aiding and abetting them.
