وحَدَّثَنَاه مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ ، عَنْ هِشَامٍ ، عَنْ يَحْيَى ، عَنْ أَبِي سَلَمَةَ ، عَنْ عَائِشَةَ ، أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، " كَانَ يُصَلِّي رَكْعَتَيْنِ بَيْنَ النِّدَاءِ وَالإِقَامَةِ مِنْ صَلَاةِ الصُّبْحِ " .
'A'isha reported: The Messenger of Allah (ﷺ) used to observe two rak'ahs of Sunnah (prayer) when he heard the Adhan and shortened them. (This hadith has been narrated by the same chain of transmitters and in the hadith narrated by Usama the words are:" When it was dawn".)
