عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنْ يَبْقَى مِنْ نُسُكِكُمْ عِنْدَكُمْ شَيْءٌ بَعْدَ ثَلَاثٍ
It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) forbade that anything from your sacrificial animals remain after three days.
