وَلَهُمَا: مِنْ حَدِيثِ عَائِشَةَ -رَضِيَ اَللَّهُ عَنْهَا-: «كَانُوا إِذَا مَاتَ فِيهِمْ اَلرَّجُلُ اَلصَّالِحُ بَنَوْا عَلَى قَبْرِهِ مَسْجِدًا» وَفِيهِ: «أُولَئِكَ شِرَارُ اَلْخَلْقِ»
Narrated 'Aishah (RA) in al-Bukhari and Muslim, “When a pious person amongst them (the Jews and Christians) died they used to build a place of worship and prostration on his grave.”
In the same Hadith is:
“Those are the worst of creatures.”
