Ibn ‘Abbas said that God’s messenger commanded his companions to substitute sacrificial animals at the <i>’umra</i> of Fulfilment (<i>‘Umra al-qada'</i> The one performed in the year after the treaty made at al-Hudaibiya) for those they had sacrificed in the year of al-Hudaibiya. Abu Dawud transmitted it.

عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ أَصْحَابَهُ أَنْ يُبَدِّلُوا الْهَدْيَ الَّذِي نَحَرُوا عَامَ الْحُدَيْبِيَةِ فِي عُمْرَةِ الْقَضَاءِ. رَوَاهُ أَبُو دَاوُدَ وَفِيهِ قِصَّةٌ وَفِي سَنَدِهِ مُحَمَّدُ بْنُ إِسْحَاقَ
