[Machine] Omar ibn Abdul Aziz asked Abu Bakr ibn Sulaiman ibn Abi Hathma about what was written during the time of the caliphate of the Messenger of Allah peace be upon him. Abu Bakr ibn Sulaiman replied that Omar ibn Khattab wrote first during the caliphate of Abu Bakr. Omar then asked who was the first person to write among the Amir al-Mu'minin (commander of the faithful)? Abu Bakr ibn Sulaiman said, "Ash-Shifa' informed me that Omar ibn Al-Khattab wrote a letter to the governor of Iraq instructing him to send two men to ask about Iraq and its people. The governor of Iraq sent Labid ibn Rabiah and Adi ibn Hatim. when they arrived in Madinah, they parked their camels in the mosque courtyard and entered the mosque. There they saw Amr ibn Al-Aas and said to him, 'Seek permission for us from Amr al-Mu'minin.' Amr al-Mu'minin replied, 'By Allah, you have hit the mark. His name is the Amir and we are the believers.' Amr al-Mu'minin then stood up, entered and said the salaam to Omar ibn Al-Khattab, 'Peace be upon you, O Amir al-Mu'minin.' Omar said, 'What do you think of this name, O son of Al-Aas? My Lord knows. You need to take back what you just said.' They replied, 'Indeed, Labid ibn Rabiah and Adi ibn Hatim have arrived. They parked their camels in the mosque courtyard and have come to speak with you.' So, the book began from that moment on." Ash-Shifa' is the paternal aunt of Abu Bakr ibn Sulaiman.
