Ibn ‘Umar (may Allah be pleased with him) was one of those who were known for being very keen to follow in the footsteps of the Prophet (blessings and peace of Allah be upon him). In this report, Nafi‘, the freed slave of Ibn ‘Umar, narrates that when ‘Abdullah ibn ‘Umar (may Allah be pleased with him) entered the Kaaba, he would seek out the place where the Prophet (blessings and peace of Allah be upon him) had prayed). So he would stand with the door behind him, and walk forward until between him and the wall in front of him there was no more than approximately three cubits, intending thereby to pray where Bilal had told him that the Prophet (blessings and peace of Allah be upon him) had prayed. A report in Sahih al-Bukhari describes the place where the Prophet (blessings and peace of Allah be upon him) prayed. Ibn ‘Umar asked Bilal: What did the Prophet (blessings and peace of Allah be upon him) do inside the Kaaba? He said: He stood with one pillar on his left, another pillar on his right, and three pillars behind him – and at that time the House was built on six pillars – then he prayed. Then Ibn ‘Umar said: There is no blame on anyone if he prays in any place in the House he wishes. What is meant is that in order for prayer inside the Sacred House to be valid, it is not stipulated that it should be offered in the same place as that in which the Prophet (blessings and peace of Allah be upon him) prayed, although that is better, even though the purpose may be achieved by praying elsewhere. This hadith may be reconciled with the hadith of Ibn ‘Abbas (may Allah be pleased with him) in Sahih al-Bukhari – in which it says: “[The Prophet (blessings and peace of Allah be upon him)] entered the Kaaba and said takbir throughout its interior, and he did not pray in it” – by noting that the affirmation of Bilal takes precedence over the negation of anyone else, because Ibn ‘Abbas (may Allah be pleased with him) was not with the Prophet (blessings and peace of Allah be upon him) on that day; rather he attributed his negation on one occasion to Usamah and on another occasion to his brother al-Fadl. It was said: It may be that the Prophet (blessings and peace of Allah be upon him) entered the Kaaba on two occasions, on one of which he prayed and on the other occasion he did not pray. This hadith indicates that the Kaaba has a door, and that it may be opened and closed according to what the situation requires. It also indicates that it is permissible to pray inside the Kaaba..
