أَخْبَرَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، قَالَ حَدَّثَنِي نَافِعٌ، أَنَّ ابْنَ عُمَرَ، حَدَّثَهُ أَنَّ حَفْصَةَ حَدَّثَتْهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُصَلِّي رَكْعَتَيْنِ خَفِيفَتَيْنِ بَيْنَ النِّدَاءِ وَالإِقَامَةِ مِنْ صَلاَةِ الصُّبْحِ .
Ibn Umar narrated that Hafsah had told him that the: Messenger of Allah (ﷺ) used to pray two brief rak'ahs between the adhan and the Iqamah of Subh prayer.
