What is the ruling on writing a Quranic verse while in a state of ritual impurity (janabah) when there is a necessity for it?

There is no harm in writing the Qur’an or anything in it—such as the Basmala (In the Name of Allah) and admonitions—for one who is in a state of minor ritual impurity (muhdith) or major ritual impurity (junub), as long as there is a need for it and it is little, or without touching or carrying theaf Mushaf (definition) (the physical copy of the Qur’an).
