1. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan from al-‘Ala’ from Muhammad ibn Muslim who has said the following: “I heard him (the Imam) (a.s.), say, ‘If you cannot find water and you decide for Tayammum, you must wait until the time (for Salah (prayer)) is about to end. If water is still not available, you do not miss the soil and the ground.’”

Translation: Muhammad Sarwar — attributed by Thaqalayn·The Arabic above is the original.

2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ibn ’Udhaynah from Zurarah who has said the following: “One of the two Imam, ‘Alayhim al-Salam, has said, ‘If during a journey water cannot be found, one must search for water as long as there is time; but when there is fear for losing time, one must then take Tayammum to perform Salah (prayer) during the end of time just before it totally ends. If later water is found, then one is not required to perform Salah (prayer) again; however, Wudu’ is necessary for future.’”

Translation: Muhammad Sarwar — attributed by Thaqalayn·The Arabic above is the original.

3. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “I once heard abu ‘Abd Allah (a.s.), say, ‘If means of cleansing (water for Ghusl (bath)) cannot be found after experiencing sexual relation, one must wipe one’s face with (soil for Tayammum) earth, then perform Salah (prayer). When water is found, Ghusl (bath) must be taken and Salah (prayer) so performed is sufficient.’”

4. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan and Ali ibn Ibrahim has narrated from his father all from Hammad ibn ‘Isa from Hariz from Zurarah who has said the following: “I once asked abu Ja‘far (a.s.), ‘Can a man pray Salaat with one Ablution (Wudhu), (including) all of the night and day prayers’. He said: ‘Yes, for as long as an event does not occur (breaking his ablution)’. I said, ‘Can he pray with one Tayammum, all of the night and day prayers?’ He said: ‘Yes, for as long as an event does not occur (breaking his Tayammum), or he finds water’. I said, ‘Supposing he does find the water and hopes that he would be able to find another water, and if he thinks that he would be to every time, but that is difficult upon him?’ He said: ‘That would break his Tayammum, and upon him is to repeat the Tayammum’. I said, ‘Supposing if he finds the water and already entered into the Salaat?’ He said: ‘Let him leave it for as long as he has not performed a bowing. If it was so that he had performed a bowing, let him continue his prayer, for the Tayammum is one of the two purifiers’.”’
