Chapter : Performing ablution after eating the flesh of camel.
Narated By Al-Bara’ ibn Azib : The Messenger of Allah (PBUH) was asked about performing ablution after eating the flesh of the camel. He replied: Perform ablution, after eating it. He was asked about performing ablution after eating meat. He replied: Do not perform ablution after eating it. He was asked about saying prayer in places where the camels lie down. He replied: Do not offer prayer in places where the camels lie down. These are the places of Satan. He was asked about saying prayer in the sheepfolds. He replied: You may offer prayer in such places; these are the places of blessing.
