Yahya related to me from Malik from Abu'z-Zubayr al-Makki fromAbu't-Tufayl Amir ibn Wathila that Muadh ibn Jabal told him that theywent out with the Messenger of Allah, may Allah bless him and granthim peace, in the year of Tabuk, and the Messenger of Allah, may Allahbless him and grant him peace, joined dhuhr with asr and maghrib withisha. Muadh said, "One day he delayed the prayer, and then came outand prayed dhuhr and asr together. Then he said, 'Tomorrow you willcome, insha' llah, to the spring of Tabuk. But you will not get thereuntil well into the morning. No one who arrives should touch any ofits water until I come.' We came to it and two men had got to itbefore us and the spring was dripping with a little water. TheMessenger of Allah, may Allah bless him and grant him peace, askedthem, 'Have you touched any of its water?' They said, 'Yes.' TheMessenger of Allah, may Allah bless him and grant him peace, reviledthem and said what Allah wished him to say. Then they took water withtheir hands from the spring little by little until it had beencollected in something. Then the Messenger of Allah, may Allah blesshim and grant him peace, washed his face and hands in it. Then he putit back into the spring and the spring flowed with an abundance ofwater and the people drew water from it. The Messenger of Allah, mayAllah bless him and grant him peace, said, 'If you live long enough,Muadh, you will soon see this place filled with gardens.' "
