Is there an explicit text from the Messenger of Allah that the caliphate belongs to Abu Bakr al-Siddiq after him?

Question:
Is there textual evidence that the caliphate belongs to Abu Bakr al-Siddiq (may Allah be pleased with him)?

Answer:
An explicit text? There is no explicit text, but there are indications. Among them, and the greatest of them, is his appointment to lead the prayer. His appointment to lead the prayer. When Aisha said that Abu Bakr was a man who weeps, meaning he cries, she asked, "Should 'Umar lead the prayer?" He said, "No, tell Abu Bakr to lead the people in prayer." So the Messenger of Allah (peace and blessings be upon him) insisted that Abu Bakr lead the people in prayer after the Messenger of Allah (peace and blessings be upon him). This is a clear indication of the caliphate. For this reason, the Companions said during the pledge of allegiance, "Are you not pleased with the Messenger of Allah (peace and blessings be upon him) for our religion, and are we not pleased with you for our worldly affairs?"
