The ruling on fiddling with the beard and other things during prayer

Question:
His second question asks: What is the ruling on one who performs certain movements during prayer, such as adjusting the head covering, fiddling with the beard, or the fingernails, or the watch, or similar things?

Answer:
The Sunnah for the believer in prayer is humility and the absence of movement. He should be at ease and humble in his prayer, and leave off movements. He places his right hand over his left on his chest, remaining still while standing. When he bows, he places his hands on his knees with his fingers spread apart, remaining still and humble, straightening his back and placing his head in line with his back in the bowing. When he rises, he is at ease in his rising and straightens up, and places his right hand over his left on his chest in the prayer after the bowing, while standing and humble. And so, when he prostrates, he says the takbir and prostrates, placing his hands with his fingers extended toward the qiblah, keeping them close together, humble to Allah, and placing them in line with his shoulders, or placing his hands in line with his ears in his prostration, while he is humble and straight in his prostration, having raised his belly from his thighs and his thighs from his lower legs. He says: “My Lord, forgive me,” and he glorifies, saying: “Glory to my Lord, the Most High,” and he supplicates to his Lord. Then he rises and sits at ease, humble to Allah , spreading his left foot and pointing his right foot forward, and placing his hands on his knees, or on his thighs. He says: “My Lord, forgive me, my Lord, forgive me,” and he supplicates. Then he prostrates, and so he is humble in all of this, and leaves off movements.
As for fiddling with his head covering, or his beard, or his watch, or his fingernails, all of this is disliked in prayer, disliked; but it does not invalidate it, it does not invalidate the prayer. However, if it becomes frequent and continuous, it invalidates it. If it becomes frequent by custom and continuous, it invalidates it. But if it is scattered and not continuous, it does not invalidate it. It is established from him (peace and blessings be upon him) that in the eclipse prayer, when Paradise was shown to him, he moved forward toward it, and when Hellfire was shown to him, he moved back. He led the people in prayer on the minbar, climbing the minbar to recite to them and bow, then descending to prostrate at the base of the minbar.
All of this indicates that these movements and similar ones do not harm the prayer. Likewise, he used to pray one day while carrying Amamah, the daughter of Zaynab. He would carry her, and when he prostrated, he would put her down, and when he stood up, he would pick her up. This indicates that such movements do not harm the prayer, because they are few and scattered.
As for the much, continuous, uninterrupted thing, this invalidates it according to the people of knowledge if it becomes frequent by custom, whether his preoccupation is with his watch, turning it over and the like, or with his beard, or with his head covering, or with anything else.
So the believer should seek humility and beware of fiddling. He should beware of fiddling in all ways, in the state of bowing, prostration, standing, and otherwise. Yes.
