عَنْ عَائِشَةَ رضي الله عنها قَالَتْ: قَالَ رَسُولُ اللهِ صلى الله عليه وسلم:
«مَنْ أَحْدَثَ فِي أَمْرِنَا هَذَا مَا لَيْسَ فِيهِ فَهُوَ رَدٌّ» متفق عليه.
ولمسلم: «مَنْ عَمِلَ عَمَلًا لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ».
[صحيح] - [متفق عليه] - [صحيح البخاري: 2697]

‘Ā’ishah (may Allah be pleased with her) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said:
"Whoever introduces into this matter of ours (Islam) something that does not belong to it shall have it rejected." [Agreed upon] A narration by Muslim reads: "Whoever does something that is not in accordance with this matter of ours shall have it rejected."
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 2697]
The Prophet (may Allah's peace and blessings be upon him) clarifies that whoever innovates something in the religion or does something that is not supported by evidence from the Qur’an and Sunnah will have it rejected and Allah will not accept it from him.
