عَنْ أَنَسٍ قَالَ: مَرَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اللَّهُ عَلَيْهِ وَسَلَّمَ بِتَمْرَةٍ فِي الطَّرِيقِ فَقَالَ: «لَوْلَا أَنِّي أَخَافُ أَنْ تَكُونَ مِنَ الصَّدَقَةِ لأكلتها»

Abu Huraira told that al-Hasan b. 'All took one of the dates of the sadaqa and put it in his mouth, whereupon the Prophet said, “Leave it alone, leave it alone,” in order that he might throw it away. He then said, “Do you not know that we* do not eat the sadaqa?’ (Bukhari and Muslim.)* The pronoun includes the Prophet and his family, al Hasan being his grandson. The idea is more definitely expressed in 'Abd al-Muttalib's tradition.
