وَعَن زاهرٍ الأسلميِّ قَالَ: إِنِّي لَأُوقِدُ تَحْتَ الْقُدُورِ بِلُحُومِ الْحُمُرِ إِذْ نَادَى مُنَادِي رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَنْهَاكُمْ عَنْ لُحُومِ الْحُمُرِ. رَوَاهُ البُخَارِيّ

Zahir al-Aslami said he was kindling fire under pots which contained asses' flesh when God's messenger's crier made an announcement to the effect that God's messenger prohibited asses' flesh to the people. Bukhari transmitted it.
