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 said that when God’s messenger was brought food he asked whether it was a present or sadaqa, and if he was informed that it was sadaqa he told his companions to eat, but did not eat himself; if however he was informed that it was a present he put in his hand and ate along with them.(Bukhari and Muslim.)
