What is the ruling on hurrying and lacking tranquility in prayer?

Question:
He also asks: What is the ruling on the prayer of an imam who hurries in prayer such that the follower is unable to recite al-Fatihah? Is his prayer valid or not? May Allah guide you.

Answer:
It is obligatory for the imam, the one praying alone, and the follower to have tranquility, for tranquility is one of the great pillars of prayer. Therefore, it is not permissible for a believer to be lax in his prayer, whether he is an imam, a follower, or praying alone. This is based on what is established in the two Sahihs from the Prophet (peace and blessings be upon him) that he said to the one who prayed poorly: . And the Prophet (peace and blessings be upon him), when he bowed, would be tranquil until every vertebra returned to its place. When he raised his head, he would straighten and be balanced until every vertebra returned to its place. When he prostrated, he would be balanced and straight until every vertebra returned to its place. And when he raised his head and sat between the two prostrations, he would be balanced and tranquil until every vertebra returned to its place. This is what is obligatory. So the imam who hurries in prayer and does not have tranquility, his prayer is not valid; rather, it is invalid. It is obligatory to warn him, and if he does not correct himself, he must be removed from the position of imam, and one should not pray behind him. He must have tranquility. It is also obligatory to recite the tasbih in the bowing and in the prostration. In the bowing, one says "Subhana Rabbi al-Azim" (Glory be to my Lord, the Most Great), and it is obligatory to say it once, but it is better to repeat it three times or more, five, six, or seven times. This is the best. The minimum for perfection is three times, recited with tranquility: "Subhana Rabbi al-Azim, Subhana Rabbi al-Azim, Subhana Rabbi al-Azim." If one increases it to five or seven, that is better, and the obligatory amount is once. And so it is in the prostration: "Subhana Rabbi al-A'la" (Glory be to my Lord, the Most High), "Subhana Rabbi al-A'la," "Subhana Rabbi al-A'la." The minimum for perfection is three times, and the obligatory amount is once. If one increases it to five, seven, or ten, that is better. It is recommended to make du'a in the prostration as well, and to strive in du'a, as came in the Sunnah from the Prophet (peace and blessings be upon him). As for hurrying and clicking (nukr), this is absolutely not permissible; rather, it invalidates the prayer. We ask Allah for safety from it. Yes.
