ahmad:7758ʿAbd al-Razzāq > Maʿmar > Muḥammad b. Ziyād > Abū Hurayrah

[Machine] He heard Abu Hurairah saying, "We were with the Messenger of Allah ﷺ when he was distributing dates from the charity to people, and Al-Hasan ibn Ali was in his lap in his room. When the Prophet ﷺ finished, he carried him on his shoulder. His saliva fell on the Prophet ﷺ , and the Prophet ﷺ lifted his head, and there was a date in it. The Prophet ﷺ put his hand inside Al-Hasan's mouth and took out the date. Then he said, "Do you not know that charity is not permissible for the family of Muhammad?"  

أحمد:٧٧٥٨حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ أَخْبَرَنِي مُحَمَّدُ بْنُ زِيَادٍ

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ كُنَّا عِنْدَ رَسُولِ اللهِ ﷺ وَهُوَ يَقْسِمُ تَمْرًا مِنْ تَمْرِ الصَّدَقَةِ وَالْحَسَنُ بْنُ عَلِيٍّ فِي حِجْرِهِ فَلَمَّا فَرَغَ حَمَلَهُ النَّبِيُّ ﷺ عَلَى عَاتِقِهِ فَسَالَ لُعَابُهُ عَلَى النَّبِيِّ ﷺ فَرَفَعَ النَّبِيُّ ﷺ رَأْسَهُ فَإِذَا تَمْرَةٌ فِي فِيهِ فَأَدْخَلَ النَّبِيُّ ﷺ يَدَهُ فَانْتَزَعَهَا مِنْهُ ثُمَّ قَالَ أَمَا عَلِمْتَ أَنَّ الصَّدَقَةَ لَا تَحِلُّ لِآلِ مُحَمَّدٍ
