Sahih al-Bukhari 435, 436
Narrated `Aisha and `Abdullah bin `Abbas:
When the last moment of the life of Allah's Messenger (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.
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، أَنَّ عَائِشَةَ، وَعَبْدَ اللَّهِ بْنَ عَبَّاسٍ، قَالاَ لَمَّا نَزَلَ بِرَسُولِ اللَّهِ صلى الله عليه وسلم طَفِقَ يَطْرَحُ خَمِيصَةً لَهُ عَلَى وَجْهِهِ، فَإِذَا اغْتَمَّ بِهَا كَشَفَهَا عَنْ وَجْهِهِ، فَقَالَ وَهْوَ كَذَلِكَ ‏
"‏ لَعْنَةُ اللَّهِ عَلَى الْيَهُودِ وَالنَّصَارَى اتَّخَذُوا قُبُورَ أَنْبِيَائِهِمْ مَسَاجِدَ ‏"‏‏.‏ يُحَذِّرُ مَا صَنَعُوا‏.‏
