This is a passage from a historical book about Sudan. The text is OCR output and contains scanning errors. I have read through them and translated the intended words, keeping proper nouns recognizable.

The passage discusses a period of time, likely related to leadership or succession. It mentions individuals like Al-Hasan bin Ali, Al-Abbas, and others, and refers to events such as pledges of allegiance and the passage of time. The text also touches upon the concept of leadership and the qualities expected of leaders, particularly in relation to youth and experience. It seems to be a historical account of political or religious events in Sudan.
