The questioner : Regarding the ruling on writing in the mushafs, such as marginal notes and the like?
The Shaykh : In the past, writing was not known, neither in the original text nor in what was written in the margins. So, some of the Salaf disliked writing anything alongside the mushaf, because the Qur'an would become mixed with the written material or other things. However, now it does not become mixed. And if this does not affect the letters, meaning that you do not write between the original text such that it becomes mixed, then there is no harm.
