First Time at the Masjid - Feeling Unsure
Assalamualaikum warahmatullahi wabarakatuhu, Today I went to the masjid for the first time and felt a bit confused. I had done wudu at home but arrived a little late for Maghrib and joined in the second rak'ah. The other people who came late with me also stayed seated, so that second rak'ah was both theirs and mine. After a while we all stood up when the imam did the third rak'ah, but I noticed he didn’t recite Surah Al-Fatiha - he just said Allahu Akbar and we all went to ruku. We waited a bit and then stood up again. After the third rak'ah we finished the prayer; I made my salam and left while some others were still sitting for a little longer. I’m a revert and I’m really confused about whether I followed everything correctly. Can someone kindly explain what likely happened and if I missed anything, and any simple tips for next time at the masjid? JazākAllāhu khayran.
