Those who said he does not repeat it and his prayer suffices him

Ata said: Two men became junub (in a state of major ritual impurity). They both performed tayammum and prayed. Then both found water within the time; one of them repeated the prayer, and the other was content with the prayer he had offered. This was mentioned to the Prophet (peace and blessings be upon him), and he said: "The one who repeated it will have a double reward, and the other's prayer is also valid."

Sayyiduna Ali (may Allah be pleased with him) said: A person in a state of major ritual impurity (junub) should wait until the end of the prayer time. If he finds water, he should perform ablution; if he does not find water, he should perform tayammum and pray. If he finds water after praying, he should take a ritual bath (ghusl) but should not repeat the prayer.

Abu Salamah said: He does not repeat the prayer.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he performed tayammum and prayed, then entered Madinah within the time of the prayer, and he did not repeat the prayer.

Ibrahim said: When a man performs tayammum and prays, and then comes upon water while still within the prayer time, after he has finished his prayer, he has completed his prayer.

Mujahid said: He does not repeat the prayer; his prayer has been completed.

Sa'id bin al-Musayyib and al-Sha'bi said: If a man prays facing other than the qiblah, or prays with tayammum, or prays while there is blood or traces of janabah (sexual impurity) on his garment, and then he finds water, whether within the prayer time or after it, he is not obliged to repeat the prayer.

Al-Hasan said: If a man finds water, he should take a ritual bath (ghusl); then, if he wishes, he may repeat the prayer, and if he wishes, he may not.

Al-Hakam bin Aban said: Ikrimah was in one group and I was in another group. Ikrimah's group had no water, so they performed tayammum and prayed. Then, when they reached water, Ikrimah said to them: "Do you see the sun above the mountains?" The people said: "No." Ikrimah said: "Even if you saw the sun, we would not repeat the prayer, because tayammum suffices us." Then, when I reached al-Janad, I met Amr bin Muslim, the student of Tawus, and I mentioned to him what Ikrimah had said. He went to Tawus and mentioned it to him, then came back to me and told me: "I mentioned Ikrimah's words to Tawus, and he said: 'He has spoken the truth.'"

Ibn Sirin said: I was on a journey for Hajj or something else, and in the last part of the night I became junub (in a state of major impurity). We had no water with us, so I performed tayammum and prayed. When the forenoon had risen, a man said: "O Abu Bakr, have you repeated your prayer?" He said: "Even if I did not find water for twenty years, would I repeat my prayer?"
