The narration reported by the Shaykh (Al-Mufid), may Allah سبحانه وتعالى support him, from Abu al-Qasim Ja‘far ibn Muhammad, from Muhammad ibn Ya‘qub, from Muhammad ibn Yahya, from Muhammad ibn al-Husayn, from Safwan, from al-‘Ala’, from Muhammad ibn Muslim, who said: I heard Imam عليه السلام say: "If you do not find water and intend to perform tayammum, delay tayammum until the end of prayer time. If water eludes you, the earth will not fail you."
