There are around 300 wells in the village of Linah, Saudi Arabia which were dug by the Jinns under the authority of Prophet Sulaiman عَلَيْهِ ٱلسَّلَامُ.
When Prophet Sulaiman عَلَيْهِ ٱلسَّلَامُ was heading Jerusalem to conquer Yemen, he and his army stayed in the village of Linah to rest.
When his army felt thirsty, they started searching for water but could not find any. At this moment one of the jinns laughed and said that “I laugh for the thirst of people and they are on the sea.”
This meant that there was water underneath the village and Prophet Sulaiman عَلَيْهِ ٱلسَّلَامُ ordered the jinns to dig wells in order to obtain water. The Jinns then beat their stick on the ground and dug wells of fresh water.
The village of Linah is situated almost 300 km from Hail towards the northern border of Saudi Arabia. Out of 300 original wells dug by Jinns, 20 are still intact.
