Saeed bin Harith narrates: I was present with Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) when a man came to him and said: O Abu Abdur Rahman! My son was in the land of Persia, where a plague spread. I made a vow that if Allah Almighty saved my son, he would go to the Ka'bah on foot. Then my son (returned alive and safe), but he passed away. So Sayyiduna Abdullah (may Allah be pleased with him) said to him: Fulfill your vow. The man said to him: I had vowed that my son would go on foot, but my son has passed away. Sayyiduna Abdullah (may Allah be pleased with him) became angry and said: Were you not forbidden from making vows? I heard the Prophet (peace and blessings of Allah be upon him) say: "Indeed, a vow does not bring anything forward or delay it, but Allah, through it, extracts wealth from the miser." (The narrator says) When I saw this situation, I said to that man: Go to Saeed bin Musayyib and ask him about this issue. He went to him and asked about this issue. Then he returned, so I asked: What answer did he give you? He said: He told me: Go on foot on behalf of your son. He asked: Is this permissible for me? So Saeed bin Musayyib said: What do you think, if your son had a debt and you paid it off, would it be considered paid on his behalf? I replied: Yes. So he said: Go on foot on behalf of your son.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: Sayyiduna Umar (may Allah be pleased with him) had made a vow during the days of ignorance that he would perform i'tikaf for one night in Masjid al-Haram. So the Prophet Muhammad (peace and blessings be upon him) said to him: Fulfill your vow.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them) narrates: Sayyiduna Umar (may Allah be pleased with him) said: O Messenger of Allah (peace and blessings of Allah be upon him)! May Allah send blessings upon you. In the days of ignorance, I made a vow that I would observe i'tikaf for one night in Masjid al-Haram. So the Prophet (peace and blessings of Allah be upon him) said: Fulfill your vow.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: Sayyiduna Umar (may Allah be pleased with him) stated that when the Prophet Muhammad (peace and blessings be upon him) returned from Hunayn, Sayyiduna Umar (may Allah be pleased with him) asked the Prophet (peace and blessings be upon him) about the vow he had made in the days of ignorance to perform i'tikaf (seclusion in the mosque) for one day. The Prophet (peace and blessings be upon him) ordered him to fulfill it. Sayyiduna Umar (may Allah be pleased with him) narrates: He went ahead of the Prophet (peace and blessings be upon him). Sayyiduna Umar (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) had sent a slave girl with me who was among the captives of Hunayn. Sayyiduna Umar (may Allah be pleased with him) narrates: I lodged her in the houses of the villagers until, when I camped, some captives of Hunayn came before me who had run out and were saying: The Messenger of Allah has set us free. So Sayyiduna Umar (may Allah be pleased with him) said to Sayyiduna Abdullah (may Allah be pleased with him): Go and set that slave girl free. Sayyiduna Abdullah (may Allah be pleased with him) narrates: So I went and I set her free.

(Imam Ibn Hibban, may Allah have mercy on him, says:) In the wording of the narration, Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) has clarified that Sayyiduna Umar (may Allah be pleased with him) had made a vow to perform i'tikaf for one night, and this is mentioned only in this narration, because the wording of this narration is: Sayyiduna Umar (may Allah be pleased with him) had made a vow to perform i'tikaf for one day. So if these words are authentically established, then it is possible that by "day" here it is meant: to perform i'tikaf along with the night of that day, and where the word "night" is used, it means that its day will be included. In this way, there will remain no contradiction between the two narrations.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) passed by a man who was walking with the support of two people between him. The Prophet (peace and blessings be upon him) inquired about him. So the people informed: He has made a vow that he will go on foot (the narrator says: that is, he will go on foot to the Ka'bah). So the Prophet (peace and blessings be upon him) said: Allah, the Exalted, is free from need of this person putting himself in hardship. The Prophet (peace and blessings be upon him) instructed that man to ride. Layth, Haql, and Awza'i all belong to the same era. Abdur Rahman bin Yaman, Yahya bin Sa'id, and Humaid belong to one era; they have narrated from each other. This has been stated by the Shaykh.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) saw a man who was walking with the support of two people between him. The Prophet (peace and blessings be upon him) inquired: What is the matter with him? The people informed: He has vowed to perform Hajj on foot. So the Prophet (peace and blessings be upon him) said: Allah is not in need of his walking; he should ride.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: A man came to the service of the Prophet (peace and blessings be upon him) and said: My sister has made a vow that she will go for Hajj on foot. The Prophet (peace and blessings be upon him) said: Tell her to ride and give expiation. (Imam Ibn Hibban, may Allah have mercy on him, says:) There is a possibility that this woman either swore an oath or made a vow to go for Hajj on foot; however, there is no expiation in a vow.
