Sahih al-Bukhari, Hadith 3873 ⓘ
Narrated `Aisha: Um Habiba and Um Salama mentioned a church they had seen in Ethiopia and in the church there were pictures. When they told the Prophet of this, he said, "Those people are such that if a pious man amongst them died, they build a place of worship over his grave and paint these pictures in it. Those people will be Allah's worst creatures on the Day of Resurrection. "
حَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ عَائِشَةَ ـ رضى الله عنها أَنَّ أُمَّ، حَبِيبَةَ وَأُمَّ سَلَمَةَ ذَكَرَتَا كَنِيسَةً رَأَيْنَهَا بِالْحَبَشَةِ، فِيهَا تَصَاوِيرُ، فَذَكَرَتَا لِلنَّبِيِّ صلى الله عليه وسلم فَقَالَ " إِنَّ أُولَئِكَ إِذَا كَانَ فِيهِمُ الرَّجُلُ الصَّالِحُ فَمَاتَ بَنَوْا عَلَى قَبْرِهِ مَسْجِدًا، وَصَوَّرُوا فِيهِ تِيكَ الصُّوَرَ، أُولَئِكَ شِرَارُ الْخَلْقِ عِنْدَ اللَّهِ يَوْمَ الْقِيَامَةِ " .
