حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ طَلْحَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ مَرَّ النَّبِيُّ صلى الله عليه وسلم بِتَمْرَةٍ مَسْقُوطَةٍ فَقَالَ " لَوْلاَ أَنْ تَكُونَ صَدَقَةً لأَكَلْتُهَا ". وَقَالَ هَمَّامٌ عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَجِدُ تَمْرَةً سَاقِطَةً عَلَى فِرَاشِي ".
