Yahya related to me from Malik from Sharik ibn Abdullah ibn Abi Namir that Abu Salama ibn Abd ar-Rahman said, "Some people heard the iqama and started to pray. The Messenger of Allah ﷺ came out and said, 'Are you doing two prayers at the same time? Are you doing two prayers at the same time?' That was about the subh prayer and the two rakas before subh."
أَنَّهُ قَالَ سَمِعَ قَوْمٌ الإِقَامَةَ فَقَامُوا يُصَلُّونَ فَخَرَجَ عَلَيْهِمْ رَسُولُ اللَّهِ ﷺ فَقَالَ أَصَلاَتَانِ مَعًا أَصَلاَتَانِ مَعًا وَذَلِكَ فِي صَلاَةِ الصُّبْحِ فِي الرَّكْعَتَيْنِ اللَّتَيْنِ قَبْلَ الصُّبْحِ
