It is narrated from Hazrat Zaid bin Thabit (may Allah be pleased with him) that when the Holy Prophet (peace and blessings be upon him) arrived in Madinah Munawwarah, I was presented to the Holy Prophet (peace and blessings be upon him). The Holy Prophet (peace and blessings be upon him) was pleased to see me. The people said, "O Messenger of Allah! This boy from Banu Najjar has memorized several surahs of the Qur'an that have been revealed to you." The Holy Prophet (peace and blessings be upon him) was surprised and said, "Zaid! Learn the script of the Jews, for by Allah, I do not trust the Jews regarding my letters." So I began to learn their writing, and not even fifteen days had passed before I had mastered it. I used to read their letters to the Holy Prophet (peace and blessings be upon him), and when the Holy Prophet (peace and blessings be upon him) would reply, I would write it.
