If i entered on the imaam during his 2nd rakaah in Maghrib and i joined him. Would i need to repeat my Salaah afyer completeing it with the Imaam?
Wa Alaikum As Salam
No, you do not have to repeat your Salah. You were supposed to continue your Salah after he made the Salam, by performing the rakaat you missed. If you did not perform your missed rakaat and you ended the Salah with the Imam, you will have to repeat it.
And Allah Knows best
