عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: أُقِيمَتْ صَلَاةُ الصُّبْحِ فَقَامَ رَجُلٌ يُصَلِّي الرَّكْعَتَيْنِ، فَجَذَبَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِثَوْبِهِ فَقَالَ: ((أَتُصَلِّي الصُّبْحَ أَرْبَعًا؟))
Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) says: The iqamah for the Fajr prayer was given, a man stood up and began to offer two sunnah rak'ahs. The Messenger of Allah (peace and blessings be upon him) pulled him by his garment and said: Are you performing four rak'ahs for the Fajr prayer?
