إِذْ جَعَلَ ٱلَّذِينَ كَفَرُوا۟ فِى قُلُوبِهِمُ ٱلْحَمِيَّةَ حَمِيَّةَ ٱلْجَٰهِلِيَّةِ فَأَنزَلَ ٱللَّهُ سَكِينَتَهُۥ عَلَىٰ رَسُولِهِۦ وَعَلَى ٱلْمُؤْمِنِينَ وَأَلْزَمَهُمْ كَلِمَةَ ٱلتَّقْوَىٰ وَكَانُوٓا۟ أَحَقَّ بِهَا وَأَهْلَهَا ۚ وَكَانَ ٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمًۭا
When those who disbelieve had set up in their hearts zealotry, the zealotry of the Age of Ignorance, then Allah sent down His peace of reassurance upon His messenger and upon the believers and imposed on them the word of self-restraint, for they were worthy of it and meet for it. And Allah is Aware of all things.

Chapter: Hajjat-ul-Wada
Narrated Hafsa:
(the wife of the Prophet) The Prophet (ﷺ) ordered all his wives to finish their Ihram during the year of Hajjat-ul-Wada`. On that, I asked the Prophet (ﷺ) "What stops you from finishing your lhram?" He said, "I have matted my hair and garlanded my Hadi. So I will not finish my Ihram unless I have slaughtered my Hadi."
