What is the ruling on one who performed tawaf and sa'y for 'Umrah without being in a state of wudu'?

Question : Honorable Shaykh, I entered the state of ihram for 'Umrah, performed tawaf and sa'y, and shaved my head. After finishing the shaving, I remembered that I was not in a state of wudu during the tawaf and sa'y, and I am still in the state of ihram. What is the ruling?

Answer : The ruling in this matter is that, according to the opinion of the majority of scholars, it is obligatory for this man, if he has taken off his ihram clothes, to put on the ihram clothes, go to the Sacred House after performing wudu, and perform tawaf and sa'y and shorten his hair a second time. This is because his first tawaf is not valid, and if the tawaf is not valid, the sa'y after it is not valid, and shaving is only done after the sa'y, and the sa'y is not valid. So he has to return after performing wudu, and perform the complete tawaf, the sa'y, and the shortening or shaving. However, the stronger opinion, which was chosen by the Shaykh al-Islam Ibn Taymiyyah, is that he owes nothing. This is because there is no valid evidence from the Messenger of Allah (peace and blessings be upon him) that purity is a condition for tawaf. And if there is no authentic hadith, we cannot invalidate the work of this person who did it believing that he was drawing near to Allah, until we have proof from Allah (Glorified and Exalted is He) of its invalidity.
This does not mean that a person should be negligent about purity in tawaf. Absolutely, purity for tawaf is prescribed without dispute. The Prophet (peace and blessings be upon him) used to perform tawaf in a state of purity. But the issue is with a person who has such a situation happen to him: do we say he must repeat his 'Umrah, meaning his tawaf and sa'y? The matter is easy if the person is in Makkah; he has to do what? No, before repeating it, he puts on the ihram clothes if he has taken them off, and performs the tawaf, sa'y, and shortening. But suppose a man traveled to Egypt, Iraq, Sham, or Yemen, and he returned; it may not be possible for him to do so. So the correct view is what the Shaykh al-Islam Ibn Taymiyyah chose: that purity is not a condition for tawaf. But this does not mean that we take it lightly; rather, we maintain it and strive for it. But if such a matter happens, we do not dare to order him to repeat the tawaf until we have an authentic, explicit hadith from the Messenger of Allah (peace and blessings be upon him).
