What is the validity of the statement that an army will attack the Ka'bah in the end times?

Question:
What is prescribed regarding visiting the grave of the Prophet (peace and blessings be upon him)? And if one visits the Prophet's Mosque (peace and blessings be upon him) and then goes to visit his grave (peace and blessings be upon him), turns toward the grave, and supplicates to the Messenger of Allah (peace and blessings be upon him), do we say that he has taken the grave as an idol?

Answer:
The prescribed action is to visit the Prophet's Mosque. He said: So the intention is to visit the mosque, you pray in it and obtain this reward, then you visit his grave (peace and blessings be upon him) following the visit to the mosque. And what is prescribed is that you stand before his face (peace and blessings be upon him) and say, "Peace be upon you, O Messenger of Allah, and Allah's mercy and blessings." If you add to that and say, "I bear witness that you have conveyed the message, fulfilled the trust, advised the Ummah, and striven in the cause of Allah with true striving, so may Allah reward you with the best reward He gives a prophet for his Ummah," there is no harm in that. However, if one supplicates to the Messenger and asks him for things, that is major shirk (associating partners with Allah). If one asks the Messenger for needs, or for forgiveness, or apologizes to him for sins, or anything else. Seeking forgiveness is for Allah, and supplication is for Allah. The Messenger is only a Messenger (peace and blessings be upon him); he conveyed the message and fulfilled the trust (peace and blessings be upon him). He has no share in worship. Worship is for Allah: supplication, seeking forgiveness, and repentance. All of this is from Allah, Glorified and Exalted is He. You only greet the Messenger. You only greet him; this is the prescribed salam. Yes.
