"When the Messenger of Allah ﷺ was on his deathbed, he had a Khamisah over his face. When his temperature rose, he would uncover his face. When his temperature rose, he would uncover his face. While he was like that he said: 'May Allah curse the Jews and Christians, for they took the graves of their Prophets as places of worship.'" (Using translation from Nasāʾī 703)
أَنَّ عَائِشَةَ وَعَبْدَ اللهِ بْنَ عَبَّاسٍ قَالَا لَمَّا نُزِلَ بِرَسُولِ اللهِ ﷺ طَفِقَ يُلْقِي خَمِيصَةً عَلَى وَجْهِهِ فَإِذَا اغْتَمَّ كَشَفَهَا عَنْ وَجْهِهِ قَالَ وَهُوَ كَذَلِكَ لَعْنَةُ اللهِ عَلَى الْيَهُودِ وَالنَّصَارَى اتَّخَذُوا قُبُورَ أَنْبِيَائِهِمْ مَسَاجِدَ يُحَذِّرُهُمْ مِثْلَ مَا صَنَعُوا
