Sunan Ibn Majah 14
حَدَّثَنَا أَبُو مَرْوَانَ، مُحَمَّدُ بْنُ عُثْمَانَ الْعُثْمَانِيُّ حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدِ بْنِ إِبْرَاهِيمَ بْنِ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ، عَنْ أَبِيهِ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " مَنْ أَحْدَثَ فِي أَمْرِنَا هَذَا مَا لَيْسَ مِنْهُ فَهُوَ رَدٌّ " .

Abu Marwan, Muhammad ibn Uthman al-Uthmani, narrated to us: Ibrahim ibn Sad ibn Ibrahim ibn Abd al-Rahman ibn Awf narrated to us, from his father, from al-Qasim ibn Muhammad, from Aishah, that the Messenger of Allah (peace and blessings be upon him) said: Whoever introduces into this affair of ours something that does not belong to it, it is rejected.
Notes and open questions — unreviewed
The Arabic says that anything introduced into this affair that is not part of it is rejected; the English witness gives the same sense.
