حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ ، حَدَّثَنَا الْمُعْتَمِرُ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا أَبُو الْعَلَاءِ بْنُ الشِّخِّيرِ ، قَالَ : " كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَنْسَخُ حَدِيثُهُ بَعْضُهُ بَعْضًا ، كَمَا يَنْسَخُ الْقُرْآنُ بَعْضُهُ بَعْضًا " .
Abu al. 'Ala' bin al-Shikhkhir said: The Messenger of Allah (ﷺ) abrogated some of his commands by others, just as the Qur'an abrogates some part with the other.
