What is the ruling on taking a Mushaf from the mosque to the house, along with hesitation, extending the back excessively in prostration, raising the voice in recitation before prayer, and fidgeting with beards and clothes during prayer without need?

It is not permissible to take the Mus'haf (copy of the Qur'an) from the mosque. The back must be straight during prostration, neither stretched nor excessively curved. Raising one's voice with recitation before the prayer is disliked if it disturbs others. As for fiddling with one's beard or clothes during prayer, it is disliked. The Sunnah is to remain still and show humility, as Allah Almighty says: "Successful indeed are the believers, those who during their prayer are humbly submissive."
