Is the reported narration about Umar ibn al-Khattab, may Allah be pleased with him, concerning the Bedouin's supplication at the grave of the Prophet, peace and blessings be upon him, authentic?

This report is false and has not been mentioned in any of the accredited books, neither with an authentic, weak, nor fabricated chain of narration. It was transmitted from Al-Asma'i, not from 'Umar ibn Al-Khattab, may Allah be pleased with him, without any chain of narration indicating its authenticity. The narration attributed to Al-Asma'i contains a number of falsehoods, including that it has no chain of narration, and that the action of the Bedouin is not a proof, in addition to phrases that are unfitting for the Prophet, peace and blessings be upon him, such as "and if You do not forgive me, Your beloved will be angry"; for the Prophet, peace and blessings be upon him, does not become angry at Allah's decree.
