Muslims paid utmost attention to the calligraphy and decoration of the Qur'an because writing the Qur'an is an act of worship and obedience to gain reward. A tradition by Prophet Mohammed reads as: "Whoever recites a letter from the Qur'an, gets a Hasanah and each one equals ten; I would not say that a preposition which is made up of three characters is one letter; rather, it is three letters" (Sahih Attarmizi). If this is the case when reading the Qur'an, then how would it be when someone writes verses well? The Prophet paid much attention from the very beginning to the importance of writing the Quran and urged his companions who were able to write to scribe it down. At the same time, he forbade his companions from writing anything he tells them other than Qur'an.
