Sahih Muslim: Book 43, Hadith 10

Mu’adh b. Jabal reported that he went along with Allah’s Apostle (ﷺ) in the expedition of Tabuk and he (the Holy Prophet) combined the prayers. He offered the noon and afternoon prayers together and the sunset and night prayers together and on the other day he deferred the prayers; he then came out and offered the noon and afternoon prayers together. He then went in and (later on) came out and then after that offered the sunset and night prayers together and then said: God willing, you would reach by tomorrow the fountain of Tabuk and you should not come to that until it is dawn, and he who amongst you happens to go there should not touch its water until I come. We came to that and two persons (amongst) us reached that fountain ahead of us. It was a thin flow of water like the shoelace. Allah’s Messenger (ﷺ) asked them whether they had touched the water. They said: Yes. Allah’s Apostle (ﷺ) scolded them, and he said to them what he had to say by the will of God. The people then took water of the fountain in their palms until it became somewhat significant and Allah’s Messenger (ﷺ) washed his hands and his face too in it, and then, took it again in that (fountain) and there gushed forth abundant water from that fountain, until all the people drank to their fill. He then said: Mu’adh, it is likely that if you live long that you see what is here filled with gardens.
