Is it permissible to wail and raise the voice in crying during the Tarawih and night prayers, given that this causes disturbance to others, preventing them from hearing the recitation?

The questioner : Is it permissible to wail and raise the voices in crying during the Tarawih and night prayers, given that this causes disturbance to others, preventing them from hearing the imam's recitation?

The Shaykh : There is no doubt that crying out of fear of Allah the Exalted is among the characteristics of the people of good and righteousness. The Prophet (peace and blessings be upon him) would become humble in his prayer, and his chest would make a sound like the bubbling of a cauldron. And Allah Blessed and Exalted is He said: .
Crying when the Qur'an is recited, during prostration, and during supplication is among the characteristics of the righteous, and a person is praised for it. The sounds that are sometimes heard from some people are, as it appears, not of their own choice; it is something they feel within themselves and hear without their own volition.
The scholars (may Allah have mercy on them) said: If a person cries out of fear of Allah, his prayer is not invalidated, even if two letters or more become apparent from it, because this is a matter over which a person cannot exercise control.
It is not possible for us to tell people: Do not be humble in prayer, do not cry in prayer.
Rather, we say: The crying that comes from the heart being affected by what it heard, or by what it visualized when it prostrates—for when a person prostrates, he visualizes that he is at his closest to his Lord the Exalted, as the Prophet (peace and blessings be upon him) said: —if the heart visualizes this while prostrating, there is no doubt that it will become humble and crying will occur. I cannot tell people to refrain from crying.
However, I say that crying out of fear of Allah, and the sound over which a person cannot exercise control, is permissible.

The questioner : A group entered the mosque while the imam was in the final tashahhud. They did not join him in the prayer; instead, they established the prayer at the back of the mosque and began the prayer while the imam had not yet concluded the prayer with the taslim. Is their prayer invalid?

The Shaykh : It is better, if you come and the imam is in the final tashahhud and you have a group with you, that you do not begin the prayer until the first group has completed it, so that two congregations do not gather in one mosque at the same time. However, if they did so and were far from the first congregation and did not disturb them, there is no harm in this.
If we come to this mosque or any other, and we have not prayed the 'Isha' prayer, and we find them praying the Tarawih prayer, we join them in the Tarawih prayer with the intention of 'Isha'. Then, if we are travelers, we conclude the prayer with the imam in the Tarawih prayer once we have prayed the two rak'ahs. If we are residents, when the imam concludes the prayer, we complete the remainder of the 'Isha' prayer. We do not establish another congregation for the 'Isha' prayer, because it is not befitting for there to be two congregations in a mosque, for this is a sign of division. Indeed, when the Messenger (peace and blessings be upon him) concluded the prayer one day and found two men secluded who had not prayed with the people, he said: . They said: O Messenger of Allah, we prayed in our tents. He said: . The Prophet (peace and blessings be upon him) ordered them to pray with the people, even though they had prayed in their tents, so that division would not occur. And he said: .
Similarly, if we enter the mosques and the people are praying the Tarawih prayer, we join them and intend it as the 'Isha' prayer. Imam Ahmad (may Allah have mercy on him) has explicitly stated this.
