باب بَيَانِ أَنَّ أَفْضَلَ الصَّدَقَةِ صَدَقَةُ الصَّحِيحِ الشَّحِيحِ ‏
Sahih Muslim 1032 c

This hadith has been narrated with the same chain of transmitters except with this change (of words):

" Which charity is most excellent?"
حَدَّثَنَا أَبُو كَامِلٍ الْجَحْدَرِيُّ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا عُمَارَةُ بْنُ الْقَعْقَاعِ، بِهَذَا الإِسْنَادِ نَحْوَ حَدِيثِ جَرِيرٍ غَيْرَ أَنَّهُ قَالَ أَىُّ الصَّدَقَةِ أَفْضَلُ ‏.‏
