Muhammad ibn Ali ibn Mahbub narrated from al-‘Abbas ibn Ma‘ruf, from ‘Abdullah ibn al-Mughira, from Mu‘awiyah ibn Maysarah, who said: I asked Abu ‘Abdullah عليه السلام about a man in travel who does not find water, then prays, and later finds water while there is still some time left (for the prayer). Should he proceed with his prayer, or should he perform wudu' and repeat the prayer? Imam عليه السلام said: "He proceeds with his prayer, for the Lord of water is also Lord of dust."
