What is the ruling on performing tawaf in a garment that contains impurity of which its owner was unaware?

The questioner : This questioner says: If a Muslim performs the tawaf for 'Umrah, then performs sa'y afterwards, and exits the state of ihram from his 'Umrah, and then it is discovered that there was impurity in his garment during his tawaf, what is the ruling on that, with the evidence?

The Shaykh : If a person performs tawaf for 'Umrah and sa'y, and afterwards finds impurity in his ihram garment, then his tawaf is valid, his sa'y is valid, and his 'Umrah is valid. This is because if a person has impurity on his garment that he did not know about, or if he knew about it but forgot to wash it and prayed in that garment, then his prayer is valid. Likewise, if he performs tawaf in this garment, his tawaf is valid. So if a man, after finishing the Friday prayer, finds impurity in his garment but he did not know about it beforehand, what is the ruling on the Friday prayer? It is valid. And if he knew about it but forgot to wash it, his prayer is valid. The evidence for this is the saying of Allah the Exalted: This is a general evidence that constitutes a great principle among the principles of the Shari'ah. There is also a specific evidence in this issue. The specific evidence in this issue is what we referred to in last night's lesson.

The questioner : The hadith that the Messenger (peace and blessings be upon him) prayed in his sandals.

The Shaykh : In this issue, the Messenger (peace and blessings be upon him) prayed with his Companions one day. It was his sunnah (recommended practice) (peace and blessings be upon him) to pray in his sandals, so the people took off their sandals. When he finished his prayer, he said, "What is the matter with you?" They said, "We saw you, O Messenger of Allah, take off your sandals, so we took off our sandals." that there was harm in them, meaning impurity. The Prophet (peace and blessings be upon him) did not repeat the prayer, even though at the beginning of his prayer he had been wearing impure shoes. This indicates that if a person prays in an impure garment while forgetting or being ignorant, his prayer is valid. Here is a question: This man was invited to a walimah (wedding feast).
And he ate from it. There was camel meat in it, cooked, soft, and delicious. So he ate from the camel meat until he was full, and he stood up to pray because he did not know that this meat was camel meat. Are you with me?

The questioner : Yes.

The Shaykh : When he finished his prayer, his companion who had invited him said, "Perhaps you performed wudu' (ablution)?" He said, "What is that?" He said, "It is the camel meat that you ate." He said, "I thought it was sheep meat because it was soft, delicious, and small in size, as it was lean and not large. So what do we say to this man who ate the meat and prayed while not knowing?

The questioner : Between the Syrians.

The Shaykh : The prayer is valid, and is there any issue with the prayer?

The questioner : Yes.

The Shaykh : He repeats the prayer. He repeats the prayer. Wait. He repeats the prayer. Why did you say that the one who prayed in an impure garment does not repeat it, but the one who ate camel meat while unaware does repeat it?

The questioner : Music.

The Shaykh : Because we have a useful and important principle. It is that obligatory acts are not dropped due to ignorance or forgetfulness, and prohibited acts are dropped due to ignorance and forgetfulness. Do you understand?
What is the evidence for this principle? Listen to the evidence that obligatory acts are not dropped due to ignorance and forgetfulness. The Prophet (peace and blessings be upon him) said: And when he finished two rak'ahs of one of the ten prayers and forgot the rest of the prayer, did he complete it when he remembered, or did he say, "By Allah, I forgot," and this is dropped due to forgetfulness? Did he complete it? Good, this is evidence that obligatory acts are not dropped due to forgetfulness. The evidence that obligatory acts are not dropped due to ignorance. The evidence that obligatory duties are not dropped due to ignorance.
A man came and prayed a prayer in which he did not settle (in the positions), then he came to the Prophet (peace and blessings be upon him) and greeted him. So he said to him: , and he repeated it three times. While he was praying, he would come and say: , until the Prophet (peace and blessings be upon him) taught him and he prayed a valid prayer. This man left an obligatory duty while ignorant. What is the obligatory duty?
Settling (in the positions), because the man said, "By Him who sent you with the truth, I do not know how to do anything other than this, so teach me." If the obligatory duty were dropped due to ignorance, the Prophet (peace and blessings be upon him) would have excused him. And this principle is useful for the student of knowledge: that obligatory acts are not dropped due to ignorance or forgetfulness, and that prohibited acts are dropped due to ignorance and forgetfulness.
