Ibrahim (may Allah have mercy on him) said: It was said that selling, buying, and writing the Qur’an for a wage was disliked. It was also said that the Mushaf is not given as inheritance, rather it is for the reciters of the household. It was also disliked to adorn the Mushaf, or to make it small or large. It was said: Honor the Qur’an and do not include unrelated things in it. Writing it in gold and placing marks at the heads of the verses was disliked. It was also said: Keep the Qur’an pure.
