باب إِنَّمَا الْمَاءُ مِنَ الْمَاءِ
Sahih Muslim 344
Abu al. 'Ala' b. 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.حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا الْمُعْتَمِرُ، حَدَّثَنَا أَبِي، حَدَّثَنَا أَبُو الْعَلاَءِ بْنُ الشِّخِّيرِ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَنْسَخُ حَدِيثُهُ بَعْضُهُ بَعْضًا كَمَا يَنْسَخُ الْقُرْآنُ بَعْضُهُ بَعْضًا .
