Hadith 1:187
Isnād Da'īf Jiddan Munkar (Zubair `Aliza'i)
Ibn ‘Umar reported God’s messenger as saying, “Some of my traditions abrogate others just as some parts of the Qur’an abrogate others.” Daraqutni transmitted it.
وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَحَادِيثَنَا يَنْسَخُ بَعْضهَا بَعْضًا كنسخ الْقُرْآن»
