Sahih al-Bukhari 7195

Kharija bin Zaid bin Thabit said that Zaid bin Thabit said, "The Prophet (ﷺ) ordered me to learn the writing of the Jews. I even wrote letters for the Prophet (ﷺ) (to the Jews) and also read their letters when they wrote to him." And 'Umar said in the presence of 'Ali, 'Abdur-Rahman, and 'Uthman, "What is this woman saying?" (the woman was non-Arab) 'Abdur-Rahman bin Hatib said:"She is informing you about her companion who has committed illegal sexual intercourse with her." Abu Jamra said, "I was an interpreter between Ibn 'Abbas and the people." Some people said, "A ruler should have two interpreters."
