Some Muslims think visiting the Prophet Mohammed’s grave is recommended or even obligatory. One of the hadeeths that these people use to justify their believes is the narration in which,
the prophet Mohammed said, “The one who come(s) to visit me in such a way that, no other cause incite him to come, so it his right upon me that I will be his intercessor on the day judgement.”
Mohammad ibn Abd-al-Hade in “Sareem al munkee” (93) said that this narration is weak per chain, and rejected (munkaar) per text.
This hadeeth was reported by Tabarani in “Awsat” (1).
Nur-Ad-Deen Heythami in “Majmau zawaid” said: “Reported by Tabarani in “Awsat”, “al-Kabeer”, in the chain Maslamat ibn Saalem, and he’s weak”.
About this narrator (Maslamat ibn Saalem) imam Abu Dawud as-Sijistane said: “Not truthful” (Mizanul itidal #8488)
