It is reported from some of the Companions regarding the story of Ibn al-Zubayr that they would raise their voices in saying "Ameen" until the mosque would shake.

The questioner : Regarding the "Ameen"... I would like to mention a point about the Companions in... and the mosque would shake with their "Ameen"; they would raise their voices.

The Shaykh: Yes.

The questioner : The scholars say: This is evidence that raising the voice in "Ameen" was not denied by anyone. I say no one denied it. The evidence is that raising the "Ameen" of the followers is a recommended practice.

The Shaykh : Yes, the answer to this is from two angles. The first angle is regarding the claim itself that the honorable professor mentioned; and that is that the scholars say: no one denied it. This principle should be understood in the correct way. We know that many matters contrary to the Sunnah occurred and were transmitted to us, yet the denial of them was not transmitted along with them. So denial must be interpreted in a broader sense. It is said, for example: It was not denied because the Sunnah was well known. I give an example that comes to mind now: Imam al-Bayhaqi narrates in his "Sunan" with a valid chain from Abdullah ibn Umar (may Allah be pleased with him) that when he called the adhan, he would say in his adhan: "Hayya 'ala khayr al-'amal" (Hasten to the best of deeds). He narrated this and did not narrate that the Companions denied it to him or to anyone else who heard it from him. We all know that the Prophetic adhan does not contain this addition, nor any addition before or after it that is known today. So what is the answer to this addition that was reported in a valid chain from Ibn Umar?
The answer is: The narrator reported this by way of information and notification, and left the ruling on it to what is established in the Sunnah of the known adhan, which is limited to the words that Muslims continue to preserve, excluding the additions before and after the adhan in some countries.
So the summary of the answer is that the non-transmission of denial does not necessitate that denial did not occur. From here, the scholars say that not knowing a thing does not necessitate knowing its non-existence. And secondly: This is a matter that occurred after the Rightly Guided Caliphs and after a long period from the death of the Messenger of Allah (peace and blessings be upon him). It is self-evident and very natural that independent legal reasoning would issue from some scholars and some rulers like Abdullah ibn al-Zubayr, and he would have his reward: if he was correct, two rewards; and if he erred, one reward. Especially since the early Salaf had the spirit to which we call Muslims today, which is the spirit of tolerance and sincere advice that does not lead to schism and the division of the word of Muslims. So it is permissible that this was the opinion of Abdullah ibn al-Zubayr, and he was the Imam. Naturally, those who follow would follow the Imam's ruling. So in that case, we are not required to follow that opinion as long as we are on clear evidence regarding the matter of the Prophet (peace and blessings be upon him).
We all know—and we are in Mina—that Uthman (may Allah be pleased with him), when he performed Hajj and stayed in Mina, would pray the full prayer; he would pray the four-rak'ah prayer as four. And some of the Companions who were with him would deny that to him personally. And yet, when this denier would pray behind Uthman and Uthman would pray the full prayer, the denier himself would pray the full prayer. Among them was Abdullah ibn Mas'ud (may Allah be pleased with him). It was said to him: How do you deny the addition to him—meaning completing the prayer—and yet you pray behind him the full prayer? He would say: "Disagreement is evil." This is a report narrated in "Sunan Abu Dawud." If it had not been narrated in "Sunan Abu Dawud," which is one of the six books of Sunan, and had been narrated in some books that were not transmitted to us, and only Uthman's completion of the prayer was transmitted to us, then if someone said: Uthman prayed the full prayer and no one denied it to him! It is possible that denial occurred but we did not know of the denial! The reality is that we know the denial of some people to Uthman for completing the prayer in Mina, and we do not know of the denial to Ibn al-Zubayr regarding making the followers behind him [pray the full prayer]. However, the issue is one of scholarly disagreement, and in matters of disagreement there is tolerance, as we said; with the attempt by the one obligated to follow the Prophet (peace and blessings be upon him) as much as he is able to do so.
