💐 In The Name Of Allah The Most Gracious The Most Merciful
📃 Summary: An Imaam who hasn't memorized the whole of the Noble Qur'an is allowed to recite from the Mushaf (copy of the Noble Qur'an) while leading the Muslims in praying Taraweeh or Tahajjud / Qiyaam Al-Layl.
Those who are praying with and behind the Imaam should not hold a Mushaf as they are supposed to concentrate in listening to the Imaam recite while looking downwards towards the position of Sujood, instead of reading the text and making unnecessary movements like folding and turning the pages.
If the Imaam has memorized the whole of the Noble Qur'an, then it is better to not carry a Mushaf so they can avoid the additional moves while praying such as frequently placing the Mushaf on a table, picking it up and searching for the page where they last read from etc.
Allah the Almighty knows best.
