(25) باب النَّهْىِ عَنِ الصَّلاَةِ، فِي مَبَارِكِ الإِبِلِ
Bara' b. Azib reported :
The Messenger of Allah (May peace be upon him) was asked about saying prayer at places where the camels kneel down. He replied; Do not say prayer at places where the camels kneel down because they are the places of devils. And he was asked about saying prayer in the fold of sheep. He replied: pray there because they are the places of blessing.
