And with this chain of narration, from al-Husayn ibn Sa'id, from Ibn Sinan, from Ibn Maskan, from al-Husayn al-‘Amiri, the servant of Mas‘ud ibn Musa, who said: Someone narrated to me that he asked Imam عليه السلام about a man who became in a state of major impurity (janabah) but could not find water, and the time for prayer arrived, so he performed tayammum with the soil. Then he passed by water but did not perform ghusl, waiting for another source of water. The time for the next prayer entered, and he still had not reached water, and he feared missing the prayer. Imam عليه السلام said: "He should perform tayammum and pray, for his first tayammum became invalid when he passed by the water and did not perform ghusl."
