When the last moment of the life of Messenger of Allah ﷺ came he started putting his 'Khamisa' on his face and when he felt hot and short of breath he took it off his face and said, "May Allah curse the Jews and Christians for they built the places of worship at the graves of their Prophets." The Prophet ﷺ was warning (Muslims) of what those had done. (Using translation from Bukhārī 435)
وَعَبْدَ اللهِ بْنَ عَبَّاسٍ ؓ قَالَا لَمَّا نَزَلَ بِرَسُولِ اللهِ ﷺ طَفِقَ يَطْرَحُ خَمِيصَةً لَهُ عَلَى وَجْهِهِ فَإِذَا اغْتَمَّ بِهَا كَشَفَهَا عَنْ وَجْهِهِ ثُمَّ قَالَ وَهُوَ كَذَلِكَ لَعْنَةُ اللهِ عَلَى الْيَهُودِ وَالنَّصَارَى اتَّخَذُوا قُبُورَ أَنْبِيَائِهِمْ مَسَاجِدَ يُحَذِّرُ مِثْلَ مَا صَنَعُوا
