The ruling on gesturing by the one praying in prayer, and the details thereof

The Shaykh : Imam Muslim narrated in his *Sahih* from Mu'awiyah ibn al-Hakam al-Sulami (may Allah be pleased with him), who said: "I prayed one day and saw the Prophet (peace and blessings be upon him). A man next to me sneezed, so I said to him, 'May Allah have mercy on you,' while in prayer. Do not be surprised, for you are living in scientific circumstances more than a thousand and four hundred years later, so scientifically you are more knowledgeable than many of the Companions, but practically you are at the lowest of the low. The point is this noble Companion, who was 'praying behind the noble Prophet, heard a man sneeze next to him and said to him: May Allah have mercy on you.' Whoever studies this biography and this issue feels completely that this Companion was a recent convert to Islam, and therefore things came out of him that we find objectionable, nay, reprehensible today, as I mentioned earlier. The other Companions were jurists, and so He noticed these looks and said, while praying, 'Hey, don't forget, he is praying.' I don't know what he is doing; he is talking in prayer. I didn't realize that talking is not permissible in prayer, so he shouted at the top of his voice: It is not the time for that now. Here is a jurisprudential benefit: in some of the Sunni schools of thought, not the innovated ones, if the one praying makes a meaningful gesture, his prayer is invalidated. If the one praying makes a meaningful gesture, his prayer is invalidated. We give an example: someone enters, you allow him to enter, and you say to him, 'Like this.' What does 'like this' mean?
The student : Come in.

The Shaykh : Come in. You allow him to enter. What does 'like this' mean? No, your prayer is invalidated. Now, consider: if it is 'like this'... Moreover, an incident occurred in the presence of the Messenger (peace be upon him), and this is an example, as we said earlier, that the Sunnah has three categories: speech, action, and approval. You see how the Messenger taught Mu'awiyah ibn al-Hakam al-Sulami that he should not talk, but he did not say to the group who looked and struck their thighs, 'Why did you do this?' This is a meaningful gesture... So this is an approved Sunnah. If a person, while praying, notices the one coming, and the one coming talks to him and he understands from him and gives him a gesture, this does not mean that his prayer is invalidated, even though there is a school of thought that says the prayer is invalidated. The point is that it seems the man understood from those looks and these strikes that he was doing something bad. I imagine now that this person is praying behind the Prophet of Islam. When the Messenger finished from here and turned to him... Go on, the imam today... What should he do with him? He should reprimand him, curse him, and so on. He might have imagined this, but his hope was dashed... because he said explicitly: He said: "When the Messenger of Allah (peace and blessings be upon him) turned to me, by Allah, he did not humiliate me, nor did he oppress me, nor did he strike me, nor did he curse me, but he only said to me: إن هذه الصلاة This prayer O so-and-so, هذه الصلاة لا يصلح فيها شيء من كلام الناس ؛ إنما هي تسبيح ، وتحميد ، وتكبير ، وتلاوة القرآن It is not permissible to talk during Salat because it consists of glorifying Allah, declaring His Greatness as well as recitation of the Qur'anRiyad as-Salihin 700 . It ended... but it did not end. He was reassured that he had made a mistake, but he was not punished for his mistake except with the Prophetic gentleness and the teaching from the revelation of the sky that nothing of these things is permissible in prayer.
