Is it considered an innovation if the imam prolongs the pause after al-Fatihah?

The questioner : If the ma'mum, the imam praying alone, or the imam makes a pause, it is an innovation, it is a position.

The Shaykh : And we see that there is nothing regarding that matter in which the scholars of the Sunnah differed; it is not said to be an innovation.
As for what the people of innovation said, yes. But as for what the scholars of the Sunnah differed on, we do not call it an innovation. Otherwise, every issue in which there is disagreement would make the one who disagrees an innovator. And who are we to judge people as innovators? Is it not possible that we are the ones who are innovating?
It is possible. Therefore, we consider this a mistake. This approach is a mistake, because the scholars of the Sunnah, the jurists, have long and extensive disagreements. Do we say to every person who disagrees that he is an innovator? Do we say, for example, to the one who performed wudu' after eating camel meat, while the other does not consider it necessary, that the one who performed wudu' is an innovator?
Do we say to the one who raised his hands during ruku' that he is an innovator, while the other does not consider it necessary? This is absolutely untenable.

The questioner : May Allah reward you. The Shaykh al-Islam (may Allah have mercy on him) considered it an innovation for the imam to recite so that the ma'mums would recite.

The Shaykh : Yes, indeed. Rather, it is for the believers to recite al-Fatihah in its entirety. That is correct.

The questioner : Even though it is a matter on which there is disagreement.

The Shaykh : No, but the scholars who said that the believers, the imams...

The questioner : Yes.
