What are the Surahs that were revealed after the Conquest of Mecca, and was Mu'awiyah, may Allah be pleased with him, one of the scribes of revelation?

Mu'awiyah ibn Abi Sufyan embraced Islam before his father during the Umrat al-Qada' (The Lesser Pilgrimage of Fulfillment), but his conversion was not publicly known until the Day of the Conquest (of Mecca) in the 8th year of Hijra. He was the brother of Umm al-Mu'minin Umm Habibah. He narrated traditions from the Prophet, peace and blessings be upon him, and others, and a great number of Companions and Tabi'un narrated from him. He was entrusted with writing letters for the Prophet, peace and blessings be upon him, and narrations concur that he used to write down the revelation. Among the surahs that were revealed after the Conquest are Al-Ma'idah and At-Tawbah, and everything said to be the last revelation, such as Surah An-Nasr and the verses of riba (usury) from Surah Al-Baqarah.
