Whoever exposes himself to fitnah and trusts in himself — Allāh removes protection from him (we seek refuge in Allāh), and leaves him to himself.
And whoever is left to himself is destroyed.
Al-Lālikā’ī reported in Uṣūl al-Iʿtiqād (1/252/153), al-Ibānah (2/459/3 / 434), ad-Dīnawarī (209/335/2), and al-Harawī in Dhamm al-Kalām (139/5): From Muḥammad ibn an-Naḍr, from al-Hārithī who said: “Whoever inclines his hearing to a person of bidʿah, protection is removed from him and he is left to himself.”
Ibn Waḍḍāḥ reported in al-Bidaʿ (118): From Kathīr Abū Saʿīd who said: “Whoever sits with a person of bidʿah, protection is removed from him and he is left to himself.”
Ibn Waḍḍāḥ also reported (124): Ibrāhīm said: “Do not sit with the people of bidʿah and do not speak to them, for I fear that your hearts will apostatize.”
Where are the people of disputes and debates so they may hear this??
This is what the people of disputes, the people of opinion, and the people of argumentation on websites and pages do not want to understand, and they have not comprehended it until now.
They think the matter is connected to strength of intellect, intelligence, and knowledge.
So you find them not fearing to listen to doubts and holding debates with the Zanādiqah, devils, and atheists.
Sufyān ath-Thawrī explains all these narrations with golden words:
Ibn Waḍḍāḥ reported in al-Bidaʿ (116): From Sufyān ath-Thawrī who said: “Whoever sits with a person of bidʿah will not be safe from one of three things:
Either he becomes a fitnah for others,
or something enters his heart by which he slips and Allāh enters him into the Fire,
or he says: ‘By Allāh, I do not care what they say, and I am confident in myself.’
Whoever feels secure from Allāh regarding his religion for the blink of an eye — Allāh will strip it from him.”
Because of this severe danger that the people of disputes today are heedless of, the Salaf greatly feared that their religion would be taken from them without them realizing it — because protection is in the Hand of Allāh.
Therefore, beware lest He strips your Tawḥīd from you while you are unaware.
