Hadith 78:11
Narrated Abu Sufyan:
That Heraclius sent for him and said, "What did he, i.e. the Prophet (ﷺ) order you?" I replied, "He orders us to offer prayers; to give alms; to be chaste; and to keep good relations with our relatives.
حَدَّثَنَا يَحْيَى، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، أَخْبَرَهُ أَنَّ أَبَا سُفْيَانَ أَخْبَرَهُ أَنَّ هِرَقْلَ أَرْسَلَ إِلَيْهِ فَقَالَ يَعْنِي النَّبِيَّ صلى الله عليه وسلم يَأْمُرُنَا بِالصَّلاَةِ وَالصَّدَقَةِ وَالْعَفَافِ وَالصِّلَةِ
