In Part Twelve, we discussed the events of the third and fourth years of the blessed Hijrah, starting from the expedition of Dhu Amarr in the month of Rabi al-Awwal of the third year, until the preemptive expedition of Badr, which took place in the month of Dhu al-Qi'dah of the fourth year of the Hijrah. Now, in Part Thirteen of the book "Al-Mutayyam," we will continue our analysis of the events that occurred after the Prophet's migration to Madinah.

In this part, we will cover the events of the fifth year of the Hijrah, beginning with the expedition of Dumat al-Jandal, which took place in the month of Rabi al-Awwal of that year, and extending to the expedition of Abdullah ibn Atik to assassinate Abu Rafi' Salam ibn Abi al-Huqaiq the Jew, which occurred in the month of Dhu al-Hijjah.

Furthermore, we will delve into the events of the sixth year of the Hijrah, starting from the expedition of Muhammad ibn Maslamah to Al-Qurta'ah in the month of Muharram of that year, and moving forward to the stage of sending messages to the kings. These messages were carried by messengers who bore glad tidings and the lights of guidance, beginning with the letter of the Prophet Muhammad (peace be upon him) to Heraclius, the Emperor of the Romans. The messenger who carried this letter was Dihyah al-Kalbi. We will also discuss the Prophet's letter to Najashi, the King of Abyssinia, which was conveyed by Amr ibn Umayyah al-Damri. Additionally, we will explore the letter sent by the Prophet Muhammad (peace be upon him) to Muqawqis, the ruler of Egypt, which was delivered by Hatib ibn Abi Balta'ah.
