A man asked the Messenger of Allah (may peace he upon him) whether he should perform ablution after (eating) mutton. He (the Messenger of Allah) said: Perform ablution it you so desire, and if you do not wish, do not perform it. He (again) asked: Should I perform ablution (after eating) camel's flesh? He said: Yes, perform ablution (after eating) camel's flesh. He (again) said: May I say prayer in the sheepfolds? He (the Messenger of Allah) said: Yes. He (the narrator) again said: May I say prayer where camels lie down? He (the Holy Prophet) said: No.  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ أَأَتَوَضَّأُ مِنْ لُحُومِ الْغَنَمِ قَالَ إِنْ شِئْتَ فَتَوَضَّأْ وَإِنْ شِئْتَ فَلاَ تَوَضَّأْ قَالَ أَتَوَضَّأُ مِنْ لُحُومِ الإِبِلِ قَالَ نَعَمْ فَتَوَضَّأْ مِنْ لُحُومِ الإِبِلِ قَالَ أُصَلِّي فِي مَرَابِضِ الْغَنَمِ قَالَ نَعَمْ قَالَ أُصَلِّي فِي مَبَارِكِ الإِبِلِ قَالَ لاَ
