Bismillah.
Hadith no. 1368 (below) is a repeat. Read it here.
Narrated Salim that his father said,
"Allah's Apostle (sallallaahu `alayhi wasallam), Usama bin Zaid (radiallaahu `anhu), Bilal (radiallaahu `anhu), and 'Uthman bin abu Talha (radiallaahu `anhu) entered the Ka'ba and then closed its door. When they opened the door I was the first person to enter (the Ka'ba). I met Bilal (radiallaahu `anhu) and asked him, "Did Allah's Apostle (sallallaahu `alayhi wasallam) offer a prayer inside (the Ka'ba)?" Bilal (radiallaahu `anhu) replied in the affirmative and said, "(The Prophet (sallallaahu `alayhi wasallam) offered the prayer) in between the two right pillars."
Today's Ahadith:
Narrated Nafi':
Whenever Ibn 'Umar (radiallaahu `anhu) entered the Ka'ba he used to walk straight keeping the door at his back on entering, and used to proceed on till about three cubits from the wall in front of him, and then he would offer the prayer there aiming at the place where Allah's Apostle (sallallaahu `alayhi wasallam) prayed, as Bilal (radiallaahu `anhu) had told him. There is no harm for any person to offer the prayer at any place inside the Ka'ba.
Narrated Isma'li bin Abu Khalid:
'Abdullah bin Abu Aufa (radiallaahu `anhu) said, "Allah's Apostle (sallallaahu `alayhi wasallam) performed the 'Umra. He performed Tawaf of the Ka'ba and offered two Rakat behind the Maqam (Abraham (`alayhissalaam)'s place) and was accompanied by those who were screening him from the people." Somebody asked 'Abdullah, "Did Allah's Apostle (sallallaahu `alayhi wasallam) enter the Ka'ba?" 'Abdullah replied in the negative.
Narrated Ibn Abbas (radiallaahu `anhu):
When Allah's Apostle (sallallaahu `alayhi wasallam) came to Mecca, he refused to enter the Ka'ba with idols in it. He ordered (idols to be taken out). So they were taken out. The people took out the pictures of Abraham (`alayhissalaam) and Ishmael (`alayhissalaam) holding Azlams in their hands. Allah's Apostle (sallallaahu `alayhi wasallam) said, "May Allah curse these people. By Allah, both Abraham (`alayhissalaam) and Ishmael (`alayhissalaam) never did the game of chance with Azlams." Then he entered the Ka'ba and said Takbir at its corners but did not offer the prayer in it.
- Prophet (sallallaahu `alayhi wasallam) did pray inside the Ka`bah. Scholars of Hadith have preferred Bilal (radiallaahu `anhu)'s report over Ibn Abbas (radiallaahu `anhu)'s report because what a person saw is a stronger proof than of what a person did not see. I suggest you read that again..
- Considering that the Prophet (sallallaahu `alayhi wasallam) did not enter the Ka`bah when `Abdullah ibn `Abbas (radiallaahu `anhu)' was watching him, it gives proof that entering Ka`bah during Tawaf/`Umrah is not necessary. If one gets to get in (Hateem, for example), well and good. If not, no issues.
- Once you're inside the Ka`bah, you can pray facing any direction. How cool is that?
I don't know if the Hateem is to be included in this or not, though..
