عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ كَانَ عَلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ خَمِيصَةٌ سَوْدَاءُ حِينَ اشْتَدَّ بِهِ وَجَعُهُ قَالَتْ فَهُوَ يَضَعُهَا مَرَّةً عَلَى وَجْهِهِ وَمَرَّةً يَكْشِفُهَا عَنْهُ وَيَقُولُ ”قَاتَلَ اللَّهُ قَوْمًا اتَّخَذُوا قُبُورَ أَنْبِيَائِهِمْ مَسَاجِدَ“ يُحَرِّمُ ذَلِكَ عَلَى أُمَّتِهِ
It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the illness of the Messenger of Allah (peace and blessings be upon him) became severe. He (peace and blessings be upon him) was wearing a black cloak. He (peace and blessings be upon him) would sometimes cover his face with it and sometimes remove it, and he said: "May Allah destroy those people who made the graves of their prophets places of prostration." In fact, by saying this, he (peace and blessings be upon him) was declaring this act forbidden for his ummah.
