حَدَّثَنَا وَكِيعٌ حَدَّثَنَا صَالِحُ بْنُ رُسْتُمَ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ أُقِيمَتْ الصَّلَاةُ وَلَمْ أُصَلِّ الرَّكْعَتَيْنِ فَرَآنِي وَأَنَا أُصَلِّيهِمَا فَدَنَا وَقَالَ أَتُرِيدُ أَنْ تُصَلِّيَ الصُّبْحَ أَرْبَعًا فَقِيلَ لِابْنِ عَبَّاسٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ نَعَمْ
مسند امام احمد بن حنبل · Hadith 3329
It was narrated that Ibn 'Abbas (RA) said: The iqamah for prayer was given and I had not prayed the two rak'ahs. He (the Prophet (PBUH)) saw me w hen I was praying them and he came close to me and said: “Do you want to pray Fajr with four (rak'ahs)?" It was said to Ibn 'Abbas: From the Prophet (PBUH). He said: Yes.
