What is the meaning of the حديث (narration) of Umar ibn al-Khattab: "Indeed, the pledge of allegiance to Abu Bakr was a sudden event (fultah) and it was completed. Verily, it was as such, but Allah averted its evil. Whoever pledges allegiance to a man without consultation from the Muslims, neither he nor the one to whom he pledged allegiance should be given allegiance, lest they be killed (taghiratan an yuqtala)"? And what is meant by "taghiratan an yuqtala" and that the pledge of allegiance to Abu Bakr was a "fultah"?

The hadith, agreed upon as authentic and narrated by Bukhari from Ibn Abbas, states that Umar (may Allah be pleased with him) said: "Let no man be deceived into saying that the Bay'ah (pledge of allegiance) to Abu Bakr was a slip and it was completed. Indeed, it was like that, but Allah protected [us from] its evil."

The meaning of "fultah" (slip/haste) has two interpretations: 1. The first: Suddenness; because the common Muslims did not wait for it, rather the senior Companions hastened to it, knowing Abu Bakr's rightful claim to the Caliphate. 2. The second: This view suggests that "fultah" refers to the last night of the sacred months, which the Arabs held in high esteem. Umar (may Allah be pleased with him) likened the days of the Messenger of Allah (peace be upon him) to the sacred months in which there was no fighting, and he likened his death to a night when corruption increases. So, the pledge to Abu Bakr came suddenly, and through it, Allah protected [us from] evil.

As for "taghratan an yuqtala" (risking being killed), it means that whoever pledges allegiance to a man without the consultation of the Muslims exposes himself and those who pledged allegiance to him to being killed.
