أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عُمَارَةَ بْنِ الْقَعْقَاعِ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَجُلٌ يَا رَسُولَ اللَّهِ أَىُّ الصَّدَقَةِ أَفْضَلُ قَالَ " أَنْ تَصَدَّقَ وَأَنْتَ صَحِيحٌ شَحِيحٌ تَأْمُلُ الْعَيْشَ وَتَخْشَى الْفَقْرَ " .
