Is the unknown person who alerted the polytheists to the Prophet's departure—may Allah bless him and grant him peace—Abu Bakr Al-Siddiq—may Allah be pleased with him—especially considering the question of how Abu Bakr came to the Prophet—may Allah bless him and grant him peace—in the cave during extreme danger?

The answer summarizes that the story of Ali sleeping in the Prophet's bed and the Prophet leaving his house after throwing a handful of dust at the polytheists is a famous story in books of سیر (biographies), and although its chains of narration are weak, such matters are treated leniently, and there is nothing objectionable in it.

As for the second report, narrated by Imam Ahmad and others, which contains more details, its chain of narration is also weak due to one of the narrators (Abu Balj), who was unique in narrating this report, and the imams of hadith (definition) saw some strangeness in it.

The claim that the unknown man who informed Quraysh of the Prophet's departure was Abu Bakr is rejected, as this claim is considered "a clear lie and falsehood," and it contradicts the authentic evidence confirming Abu Bakr's companionship with the Prophet during the Hijra, and that he was sought by Quraysh.

The answer emphasizes that the weakness of these reports cannot contradict the honor of Abu Bakr's companionship with the Prophet during the Hijra, as established in the authentic hadiths in Bukhari and other collections. It also clarifies that the Prophet's departure to Abu Bakr's house at noon is not problematic.

The answer concludes by stating that what this innovator said in accusing Abu Bakr is a pure fabrication and lie, and advises Muslims to avoid listening to the people of innovation and their doubts, and mentions the sayings of the predecessors warning against sitting with the people of innovation and looking into their books.
