What is the ruling on praying inside the Hajar?

Question:
One of the brothers informed me that there is no text regarding praying inside the Hajar. What is the accuracy of that?

Answer:
The Hajar is mostly part of the Ka'bah; it is mostly part of the Ka'bah. Praying in it is praying in the Ka'bah, inside the Ka'bah. The one who says that nothing has been reported about it does not know that the Messenger (peace and blessings be upon him) entered the Ka'bah in the year of the Conquest and prayed two rak'ahs in it. He entered the Ka'bah in the year of the Conquest and prayed two rak'ahs in it, (peace and blessings be upon him). The voluntary prayer, the voluntary prayer inside the Ka'bah, is a sunnah (recommended practice).
It is the sunnah (recommended practice) of the Messenger (peace and blessings be upon him). So this Hajar is mostly part of the Ka'bah, and therefore it is called al-Hatim because it is a fragment of the Ka'bah. When Quraysh wanted to build the Ka'bah, their funds were insufficient, and they did not build it except with good money and lawful money.
So they gathered good and lawful money, but it was not enough to build the entire Ka'bah. So they fell short of part of it and built it in the state you see now, leaving the rest on the northern side. That part is of the Ka'bah, so the obligatory prayer is not valid in it.
As for the voluntary prayer, it is prayed in the Hajar. Whoever prays it in the Hajar has prayed it in the Ka'bah, inside the Ka'bah.
