Does disagreeing with the imam in prayer lead to harm?

Question : Thank you. No, by Allah, O Adhi, how? If one of the people leaves.

Answer : Yes, it leads to the fact that you have opposed what the Companions used to do, which was to agree with their imams. If you are now with the imam and you are a traveler, and he is praying four rak'ahs, you leave the sunnah, which is praying two rak'ahs, in order to agree with your imam. For this reason, I urge people, from this place and from other places, not to let their hearts differ over differences of opinion. This is what has harmed people; nothing has harmed the Ummah except this, namely that everyone says, "No, I will follow my own opinion." And if one is in a position where following and agreeing is commanded, and he opposes it, that is not correct, and it does not serve the public benefit. Perhaps one day it will become clear to you that what you are doing today is wrong, and this happens often. A person may see today that a certain opinion is correct, and one day see that the opinion held by his companion is the correct one. So, for example, if we sow discord and cast differences among the Muslims, whereas the Companions differed in matters greater than this, they differed regarding the prayer and its time, but their hearts were united and in agreement. When the Messenger (peace and blessings be upon him) urged them to go out to Banu Qurayzah, he said, "Let no one pray the 'Asr prayer except in Banu Qurayzah." They all went out, and the prayer time caught up with them. Some of them said, "We will pray so that we do not delay the prayer beyond its time." Others said, "We will not pray except in Banu Qurayzah, following the apparent text." That reached the Prophet (peace and blessings be upon him), and he did not rebuke either of the two groups. And yet, there was never anything in the heart of one against the other. So in such matters, we should not sow discord or open opposition among the Muslims as long as agreement is possible.
