"The Messenger of Allah commanded us to perform ablution after eating camel meat but not to perform ablution after eating the mutton." (Using translation from Ibn Mājah 495)
أَمَرَنَا رَسُولُ اللهِ ﷺ أَنْ نَتَوَضَّأَ مِنْ لُحُومِ الْإِبِلِ وَلَا نَتَوَضَّأَ مِنْ لُحُومِ الْغَنَمِ وَأَنْ نُصَلِّيَ فِي دِمَنِ الْغَنَمِ وَلَا نُصَلِّيَ فِي عَطَنِ الْإِبِلِ
