عن عائشة رضي الله عنها قالت: قال رسول الله صلى الله عليه وسلم : "من أحدث في أمرنا هذا ما ليس منه فهو رد " وفي رواية " مَن عَمِلَ عملًا ليس عليه أمرُنا فهو رَدٌّ". [صحيح] - [متفق عليه] المزيــد ...
‘Ā'ishah (may Allah be pleased with her) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever introduces into this matter of ours (meaning Islam) something that does not belong to it shall have it rejected."
Another narration reads: "Whoever does something that is not in accordance with this matter of ours shall have it rejected." Sahih/Authentic. - [Al-Bukhari and Muslim]
Every action or saying that does not comply with the Islamic Shariah in every aspect – that is to say, the texts and rules of Shariah do not support it – it is rejected and not accepted from the one who did it or said it.
The ruler’s judgment does not change the essence of the matter, as indicated by the words: “contrary to our matter.” The matter here means the religion.
The religion is founded upon the Shariah.
All creed-related and action-related religious innovations are false, like Ta‘tīl (denying Allah’s attributes), irjā’ (postponement), denying destiny, and accusing people of disbelief on account of their sins, as well as innovated acts of worship.
Religion is not based on personal opinions and juristic discretion.
It points to the perfection of the religion.
Everything newly introduced into the religion, inconsistent with the Shariah, should be rejected. The other version states that we should abandon every religious innovation, whether its doer is the one who introduced it or someone else before him.
All prohibited contracts are null and void, and their resultant effects are thereby non-effective.
Prohibition entails voidness, for all prohibited things are not part of the religion and so should be rejected.
