24) باب مَنْ تَصَدَّقَ فِي الشِّرْكِ ثُمَّ أَسْلَمَ

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا هِشَامٌ، حَدَّثَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ حَكِيمِ بْنِ حِزَامٍ ـ رضى الله عنه ـ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَرَأَيْتَ أَشْيَاءَ كُنْتُ أَتَحَنَّثُ بِهَا فِي الْجَاهِلِيَّةِ مِنْ صَدَقَةٍ أَوْ عَتَاقَةٍ وَصِلَةِ رَحِمٍ فَهَلْ فِيهَا مِنْ أَجْرٍ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏‏‏.‏ "‏ أَسْلَمْتَ عَلَى مَا سَلَفَ مِنْ خَيْرٍ ‏"
