Sayyiduna Usamah bin Zaid (may Allah be pleased with him) says: I entered the House of Allah (the Ka'bah) with the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) sat there and praised and glorified Allah, and proclaimed His greatness and oneness. Then he stood facing the part of the House of Allah in front of him and placed his chest, cheek, and hands upon it. Then he proclaimed the greatness and oneness of Allah and supplicated as well. Then the Messenger of Allah (peace and blessings be upon him) did the same at all the corners. Then he (peace and blessings be upon him) came out and, standing at the door, faced the Qiblah and said two or three times: This is the Qiblah, this is the Qiblah.

Ibn Jurayj says that I asked Ata: Did you hear Sayyiduna Abdullah ibn Abbas (may Allah be pleased with him) saying that you have only been commanded to perform Tawaf of the House of Allah, not to enter it? He replied: He did not prohibit entering it, but I heard him narrate: Sayyiduna Usama ibn Zayd (may Allah be pleased with him) told me that when the Prophet Muhammad (peace and blessings be upon him) entered the House of Allah, he supplicated in all its corners and did not perform prayer until he came out. After coming out, he performed two rak‘ahs facing the Qiblah and said: This is the Qiblah.

It is narrated from Amr bin Dinar that Sayyiduna Abdullah bin Umar (may Allah be pleased with him) related from Sayyiduna Bilal (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) had prayed inside the House of Allah (the Ka'bah). He said: Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) used to narrate that the Prophet (peace and blessings be upon him) did not pray inside it, but rather proclaimed takbeer (declared the greatness of Allah) at its various corners.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with him): that he asked Bilal (may Allah be pleased with him): Did the Messenger of Allah (peace and blessings be upon him) pray inside the Ka'bah? He replied: Yes, he prayed two rak'ahs between two pillars.

It is narrated from Sayyiduna Usman bin Talha (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) entered the House of Allah and prayed between the two pillars that are in front of you when you enter.
