Sahih Bukhari, Chapter: Cultivation and Agriculture

While the Prophet (SAW) was passing the night at his place of rest in Dhul-Hulaifa in the bottom of the valley (of Al-Aqiq), he saw a dream and it was said to him, "You are in a blessed valley." Musa said, "Salim let our camels kneel at the place where 'Abdullah used to make his camel kneel, seeking the place where Allah's Apostle (SAW) used to take a rest, which is situated below the mosque which is in the bottom of the valley; it is midway between the mosque and the road."
