And you claim the AULIYAH and Anbiya listen to us from their graves??
How the Prophet peace be upon him taught tawheed beautifully.
When Allah revealed: ‘O you who believe! Raise not your voices above the voice of the Prophet.’ (49.2) Ibn Az-Zubair said, “Since the revelation of this Verse, `Umar used to speak in such a low tone that the Prophet (ﷺ) had to ask him to repeat his statements.” [Bukhari Book 65, Hadith 4845]
When the Prophet peace be upon him had to ask Umar ibn Al khattab ra to repeat his statement when he was In front of him. Then how on earth he peace be upon him could hear your “Ya Muhammad madad” while he is resting in his grave?
That is how Allah taught tawheed through the Prophet peace be upon him to his companions and ummah.
Note: Miracles are exceptions.
