Is it established from the Prophet (peace and blessings be upon him) that he said, “Whoever visits me after my death, my intercession becomes obligatory for him”?

Question:
The Honorable Shaykh, may Allah grant you success, says: Is it established from the Prophet (peace and blessings be upon him) that he said: after my death, my intercession becomes obligatory for him.

Answer:
All the hadiths narrated regarding visiting his grave (peace and blessings be upon him) after Hajj or at any other time are all invalid, as the masters of preservation among the hadith scholars have pointed out. No hadith specifically concerning the visitation of his grave is valid, established, or suitable for use as evidence. Rather, visiting his grave (peace and blessings be upon him) falls under the generality of his statement (peace and blessings be upon him): “Visit the graves, for they remind you of the Hereafter.” If the graves of Muslims are visited to make du'a for the deceased and to greet them with salam, then his grave (peace and blessings be upon him) is all the more so. And just as the Companions (may Allah be pleased with them) used to greet him with salam when they arrived from a journey.
As for the specific visitation of his grave, no hadith suitable for use as evidence has been transmitted regarding it. Al-Subki attempted to force these hadiths into use as evidence, but the masters of preservation refuted him, and the most eloquent of them in refutation was Al-Hafiz Ibn 'Abd al-Hadi in his book Al-Sarim al-Manki fi al-Radd 'ala al-Subki.
