Seeking Blessing from the Walls of the Ka'bah and Clarification of What Is Prescribed

Question:
Honorable Shaykh, may Allah grant you success. The questioner asks: Is seeking blessing (tabarruk) from the walls of the Ka'bah prescribed, or is it only from a part of it? We ask for a specific clarification because...

Answer:
What has been transmitted regarding seeking blessing from the Ka'bah is that it is circumambulated, and the Yemeni Corner and the Black Stone are touched. This is what has been transmitted: touching the Yemeni Corner with the hand, wiping it with the hand, because it is on the foundations of Ibrahim, and touching the Black Stone because the Prophet (peace and blessings be upon him) touched it and kissed it during his circumambulation. As for the two Sham corners, they are inside the Ka'bah and not on the foundations of Ibrahim, because the Hatim was cut off from it when the funds of Quraysh became insufficient. They did not build the Ka'bah except with lawful money. When the money they had gathered became scarce and was not enough to build the Ka'bah on the foundations of Ibrahim, they cut off the Hatim, which is located to the north of the Ka'bah, and built what they built of it. It has remained so ever since.
When the Prophet (peace and blessings be upon him) was in his time, he said to 'A'ishah: If your people were not recently converted to Islam, or recently emerged from shirk, I would have demolished the Ka'bah and rebuilt it on the foundations of Ibrahim. So he left this out of fear of fitnah, out of fear of fitnah that people would say, "Muhammad demolished the Ka'bah and altered it." So he left it. This is an instance of leaving something when a greater harm would result from it, in order to avert fitnah. When the time of Ibn al-Zubayr (may Allah have mercy on him and be pleased with him) came, and Ibn al-Zubayr had taken control of Makkah and Iraq, he demolished the Ka'bah and rebuilt it on the foundations of Ibrahim, and made two doors for it, one from the east and one from the west. When the time of the Umayyads came, through al-Hajjaj ibn Yusuf, and they killed Ibn al-Zubayr as a martyr (may Allah the Exalted be pleased with him and his father), al-Hajjaj demolished it and rebuilt it according to the construction of Quraysh, and removed the Hatim, which is the stone of Isma'il, and restored it to the state it was in during the pre-Islamic age of ignorance (jahiliyyah), all in defiance of Ibn al-Zubayr.
When the Abbasid al-Mansur, Abu Ja'far al-Mansur, came, he wanted to restore the Ka'bah to the foundations of Ibrahim. So he consulted Malik (may Allah have mercy on him), Imam Malik. Malik said: No, the Ka'bah should not be in the hands of kings. So it remained as it was, out of fear of fitnah. And the Prophet (peace and blessings be upon him) used to say to 'A'ishah: But he left it out of fear of fitnah. So it remained, and praise be to Allah, and the good is in what exists.
If fitnah is feared regarding something, even if that thing is good, it is left in order to avert the fitnah.
