حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ بْنُ حُمَيْدٍ، قَالاَ أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، بِهَذَا الإِسْنَادِ ح وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ حَكِيمِ بْنِ حِزَامٍ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَشْيَاءَ كُنْتُ أَفْعَلُهَا فِي الْجَاهِلِيَّةِ - قَالَ هِشَامٌ يَعْنِي أَتَبَرَّرُ بِهَا - فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَسْلَمْتَ عَلَى مَا أَسْلَفْتَ لَكَ مِنَ الْخَيْرِ " . قُلْتُ فَوَاللَّهِ لاَ أَدَعُ شَيْئًا صَنَعْتُهُ فِي الْجَاهِلِيَّةِ إِلاَّ فَعَلْتُ فِي الإِسْلاَمِ مِثْلَهُ .
Ishaq ibn Ibrahim and Abd ibn Humayd narrated to us; they said: Abd al-Razzaq informed us; Ma'mar informed us, from al-Zuhri, with this chain. (Another chain:) Ishaq ibn Ibrahim informed us; Abu Mu'awiyah narrated to us; Hisham ibn Urwah narrated to us, from his father, from Hakim ibn Hizam, who said: I said: ‘Messenger of Allah, what of the good deeds I used to do during the Age of Ignorance’—Hisham explained: meaning acts of piety—‘?’ The Messenger of Allah replied: ‘You have embraced Islam with the good you did before.’ I said: ‘By Allah, I will not leave undone any good deed I performed during the Age of Ignorance without doing its like in Islam.’
