وَيَقُولُ ٱلَّذِينَ ءَامَنُوا۟ لَوْلَا نُزِّلَتْ سُورَةٌۭ ۖ فَإِذَآ أُنزِلَتْ سُورَةٌۭ مُّحْكَمَةٌۭ وَذُكِرَ فِيهَا ٱلْقِتَالُ ۙ رَأَيْتَ ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ يَنظُرُونَ إِلَيْكَ نَظَرَ ٱلْمَغْشِىِّ عَلَيْهِ مِنَ ٱلْمَوْتِ ۖ فَأَوْلَىٰ لَهُمْ
And those who believe say: If only a surah were revealed! But when a decisive surah is revealed and war is mentioned therein, thou seest those in whose hearts is a disease looking at thee with the look of men fainting unto death. Therefor woe unto them!

(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?"
