RECAUTIONARY ORDERS
The Prophet was fully aware of the poisonous and fast winds and the violent storms of that area, which at times overtook the men and the camels and buried them under the mounds of sand and dust. He, therefore, ordered that the knees of the camels should be tied and none should go out of the camping place alone at night. Experience proved that the precautionary orders given by the Prophet were very useful, because two men belonging to the tribe of Bani Sa'idah violated them and came out of the camping-place alone at midnight with the result that the intense storm suffocated one of them and flung the other on a hill. The Prophet came to know about it and was very much unhappy for those who lost their lives on account of their indiscipline. He, therefore, asked the soldiers once again to maintain discipline.[633]
'Abbad bin Bishr, who headed a group which was responsible for the safety and security of the army of Islam, reported to the Prophet that the Muslim soldiers had become involved in difficulties owing to shortage of water, and the entire storage of water was likely to be finished soon. Hence, some of them slaughtered very precious camels to utilize the water available in their bellies, and others had submitted to the Divine will and were awaiting anxiously the blessing of Allah.
The Almighty Allah, who had promised victory to His Prophet, once again helped him and his faithful companions. Torrential rains came and all drank water to their fill. Furthermore, those appointed to stock provisions, as well as the entire army, stored as much water as they desired.
