Anas b. Malik reported that the Messenger of Allah found a date and said: Were it not (that I fear) it may be part of sadaqa, I would have eaten it.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم وَجَدَ تَمْرَةً فَقَالَ " لَوْلاَ أَنْ تَكُونَ صَدَقَةً لأَكَلْتُهَا " .
