Is it permissible to perform Tahajjud prayer while reciting the Qur’an from the Mus-haf, holding it and placing it on a stand during bowing and prostration? And do these numerous movements invalidate the prayer?

According to some scholars, it is permissible to recite Tahajjud from the Mushaf (Qur'an copy), and the accompanying movements for placing and taking the Mushaf do not invalidate it. They cite the action of Dhakwan, the mawla of Aisha, as evidence. However, others, such as the Hanafis, consider the prayer invalid in such a case. Therefore, it is advisable to refrain from reciting Tahajjud from the Mushaf and suffice with what one has memorized, in order to avoid disagreement. But if the action is an imitation of those who permit it, then there is no harm in it.
