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]

‘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.
