Arabic (Original)
حَدَّثَنَا الْخُزَاعِيُّ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ الْعُمَرِيُّ عَنِ الْقَاسِمِ بْنِ غَنَّامٍ عَنْ جَدَّتِهِ الدُّنْيَا عَنْ أُمِّ فَرْوَةَ وَكَانَتْ قَدْ بَايَعَتْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَتْ سُئِلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ أَفْضَلِ الْعَمَلِ فَقَالَ الصَّلَاةُ لِأَوَّلِ وَقْتِهَا.

al-Khuza'i narrated to us: Abdullah ibn Umar al-Umari informed us, from al-Qasim ibn Ghannam, from his grandmother al-Dunya, from Umm Farwah - who had given the pledge of allegiance to the Messenger of Allah, peace and blessings be upon him - who said: The Messenger of Allah, peace and blessings be upon him, was asked about the best of deeds, and he said, "Prayer at its earliest time."
