عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يُصَلِّي الرَّكْعَتَيْنِ قَبْلَ صَلَاةِ الْفَجْرِ، كَأَنَّ الْأَذَانَ فِي أُذُنَيْهِ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) would perform the two rak'ahs before the Fajr prayer so quickly that it seemed as if the call to prayer was still in his ears.
