A few days ago I went to the masjid for the first time in ramadan. I prayed the 2 rakkats that we're suppose to pray when entering the masjid. Then when it was time to pray qiyyam illayl witr in congregation, the imam told us to get ready so we ladies stood next to each other in lines. Then the imam said Allahu Akbar and started with surat alfaiha. My question is: Aren't we suppose to say Allahu Akbar and then say the Subhanaka dua and then surah alfatiha?
