حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الْخُزَاعِيُّ، وَعَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، قَالاَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ، عَنِ الْقَاسِمِ بْنِ غَنَّامٍ، عَنْ بَعْضِ، أُمَّهَاتِهِ عَنْ أُمِّ فَرْوَةَ، قَالَتْ سُئِلَ رَسُولُ اللَّهِ صلى الله عليه وسلم أَىُّ الأَعْمَالِ أَفْضَلُ قَالَ " الصَّلاَةُ فِي أَوَّلِ وَقْتِهَا " . قَالَ الْخُزَاعِيُّ فِي حَدِيثِهِ عَنْ عَمَّةٍ لَهُ يُقَالُ لَهَا أُمُّ فَرْوَةَ قَدْ بَايَعَتِ النَّبِيَّ صلى الله عليه وسلم أَنَّ النَّبِيَّ صلى الله عليه وسلم سُئِلَ .
