Abu Huraira told that al-Hasan b. 'All took one of the dates of the <i>sadaqa</i> and put it in his mouth, whereupon the Prophet (ﷺ) 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 <i>sadaqa</i>?’ (Bukhari and Muslim.) * The pronoun includes the Prophet (ﷺ) and his family, al Hasan being his grandson. The idea is more definitely expressed in 'Abd al-Muttalib's tradition.

وَعَنْ أَبِي هُرَيْرَةَ قَالَ: أَخَذَ الْحَسَنُ بْنُ عَلِيٍّ تَمْرَةً مِنْ تَمْرِ الصَّدَقَةِ فَجَعَلَهَا فِي فِيهِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «كِخْ كِخْ» لِيَطْرَحَهَا ثُمَّ قَالَ: «أما شَعرت أَنا لَا نَأْكُل الصَّدَقَة؟»
