What is the authenticity of the hadith that mentions fifteen punishments for abandoning prayer: six in this world, three at the time of death, three in the grave, and three on the Day of Resurrection?

The Hadith "Whoever is negligent in prayer, Allah will punish him with fifteen punishments..." is a fabricated and forged Hadith falsely attributed to the Prophet, peace and blessings be upon him, as clarified by preservation scholars such as Al-Dhahabi and Ibn Hajar. The Permanent Committee for Scholarly Research and Ifta also issued a fatwa declaring it null and void. There are sufficient authentic verses and Hadiths concerning prayer and the punishment for those who abandon it, such as Allah's saying: (What has caused you to enter Saqar? They will say: "We were not of those who used to offer As-Salat (the prayers).") [Quran 74:42-43], and the Prophet's saying, peace and blessings be upon him: "The covenant between us and them is prayer; whoever abandons it has disbelieved." It is not permissible to disseminate a fabricated Hadith except with a clear statement that it is forged.
