Hadith Q595

وَالْبَيَانِ عَلَى أَنَّ وَضْعَ الْيَدَيْنِ عَلَى الرُّكْبَتَيْنِ نَاسِخٌ لِلتَّطْبِيقِ، إِذِ التَّطْبِيقُ كَانَ مُقَدَّمًا، وَوَضْعُ الْيَدَيْنِ عَلَى الرُّكْبَتَيْنِ مُؤَخَّرًا بَعْدَهُ، فَالْمُقَدَّمُ مَنْسُوخٌ، وَالْمُؤَخَّرُ نَاسِخٌ‏.‏
And the explanation that placing both hands on both knees abrogates the act of *tadbeeq*—because the act of *tadbeeq* was earlier, and the act of placing both hands on the knees came after it. Therefore, the earlier act is abrogated and the later act is the abrogator.
