A man who was travelling performed Maghrib then another group came and he wanted to join them, is it permissible for him to join their jamaa and pray with them Maghrib with the intention of praying Isha whereby he remains seated after the first tashahud and wait till he does taslim with the Imam at the same time, or he does taslim when the Imam is standing up for 3rd rak’ah.
صلاة المغرب خلف من يصلي العشاء

Praise be to Allah, and may Allah’s peace and blessings be upon the Messenger of Allah, his family and his companions.
As to what follows:
With regards to answering your question we say, success is by Allah Almighty.
What is obligatory for him according to the view of many scholars is to make 4 rak’ats Isha, in this case it is not permissible for him to do qasr (praying Isha 2 rak’ats) because he is following an imam who is performing swalah with more rak’ats than his, so if he joins the Imam then it is obligatory to complete 4 rak’ats.
Ibn Abas was asked regarding praying swalah with complete rak’ats in Makkah and shortening in Mina and he said: it is sunnah to do that.
Some scholars are of the view that it is permissible to do qasr in this case whether joined the Swalah from its beginning or he got less than 2 rak’ats or less than that. What is correct is that it is not permissible
