[Machine] I said, "O Messenger of Allah, do you think there is anything that I used to do in the pre-Islamic era which I can continue doing?" Hisham meant, "Do you find an excuse for it?" The Messenger of Allah ﷺ said, "You have embraced Islam on whatever belonged to the past." I said, "O Messenger of Allah, there is nothing that I did in the pre-Islamic era for the sake of Allah except that I continue to do it for Allah in Islam as well." He said, "Then, you shall be rewarded for freeing one hundred slaves in the pre-Islamic era, and you shall be rewarded for freeing the same number of slaves in Islam. And you shall be rewarded for sending out a hundred camels in the pre-Islamic era, and you shall be rewarded for sending out the same number in Islam."  

البيهقي:٢١٥٩٧أَخْبَرَنَا أَبُو صَالِحِ بْنُ أَبِي طَاهِرٍ الْعَنْبَرِيُّ أنبأ جَدِّي يَحْيَى بْنُ مَنْصُورٍ الْقَاضِي ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا هَنَّادُ بْنُ السَّرِيِّ ثنا أَبُو مُعَاوِيَةَ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ حَكِيمِ بْنِ حِزَامٍ قَالَ

قُلْتُ يَا رَسُولَ اللهِ أَرَأَيْتَ شَيْئًا كُنْتُ أَتَحَنَّثُ بِهِ فِي الْجَاهِلِيَّةِ؟ قَالَ هِشَامٌ يَعْنِي أَتَبَرَّرُ بِهِ فَقَالَ رَسُولُ اللهِ ﷺ أَسْلَمْتَ عَلَى صَالِحِ مَا سَلَفَ لَكَ فَقَالَ يَا رَسُولَ اللهِ لَا أَدَعُ شَيْئًا صَنَعْتُهُ فِي الْجَاهِلِيَّةِ لِلَّهِ إِلَّا صَنَعْتُ لِلَّهِ فِي الْإِسْلَامِ مِثْلَهُ قَالَ فَكَانَ أَعْتَقَ فِي الْجَاهِلِيَّةِ مِائَةَ رَقَبَةٍ فَأَعْتَقَ فِي الْإِسْلَامِ مِثْلَهَا مِائَةَ رَقَبَةٍ وَسَاقَ فِي الْجَاهِلِيَّةِ مِائَةَ بَدَنَةٍ وَسَاقَ فِي الْإِسْلَامِ مِائَةَ بَدَنَةٍ  

أَخْرَجَهُ مُسْلِمٌ فِي الصَّحِيحِ مِنْ حَدِيثِ أَبِي مُعَاوِيَةَ وَابْنِ نُمَيْرٍ عَنْ هِشَامٍ وَأَخْرَجَهُ الْبُخَارِيُّ مِنْ حَدِيثِ أَبِي أُسَامَةَ عَنْ هِشَامٍ
