وَعَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَرَّ عَلَيْهِ حِمَارٌ وَقَدْ وُسِمَ فِي وَجْهِهِ قَالَ: «لَعَنَ اللَّهُ الَّذِي وَسَمَهُ»
He reported the Prophet (sallallahu alayhi wa sallam) as saying when an ass which had been branded on its face passed him, “God curse the one who branded it!”
