What does one do if he wants to combine the two prayers and arrives at the mosque while the imam is praying the 'Isha' prayer?

The Shaykh: Yes.
Al-Halabi: Peace be upon you.

The Shaykh: And upon you peace.
Al-Halabi : How is our Shaykh doing?

The Shaykh : Praise be to Allah, I am well.
Al-Halabi : May Allah keep you well, my professor. How is your health today, may it be better, if Allah wills?

The Shaykh : Things are going well, praise be to Allah.
Al-Halabi : We ask Allah, Glorified and Exalted is He, for your recovery, my professor.

The Shaykh : How are you doing?
Al-Halabi : May Allah bless you and keep you alive, our Shaykh.

The Shaykh : How is everyone doing?
Al-Halabi : By Allah, all the brothers are well and they send their greetings to you.

The Shaykh : Peace and mercy of Allah and His blessings be upon you and them.

The questioner : Our Shaykh, I have a question and a point of inquiry.

The Shaykh: Go ahead.
Al-Halabi : May Allah reward you with good.

The Shaykh : May Allah preserve you.
Al-Halabi : The question is: A brother asks about the issue of combining prayers. If he arrives during 'Isha' and catches three rak'ahs with them, which are Maghrib for him, is it permissible for him, if the imam has finished and he is alone, to complete the combination as 'Isha'?

The Shaykh : That is what appears to be the case, as long as he arrived at the mosque. That is what appears to be the case, as long as he arrived at the mosque.
Al-Halabi : May Allah reward you with good, my professor.
