Hadith 17:983
Waki' narrated to us, from Shu'bah, from Muhammad ibn Ziyad, from Abu Hurayrah, that the Prophet, may Allah bless him and grant him peace, was brought a date from the charity (sadaqah). Al-Hasan ibn Ali took a date and chewed it in his mouth. The Prophet, may Allah bless him and grant him peace, said to him, "Kakh, kakh! Charity is not lawful for us."
حدثنا وكيع عن شعبة عن محمد بن زياد عن أبي هريرة أن النبي صلى الله عليه وسلم أتي بتمرة من الصدقة فتناول الحسن بن علي تمرة فلاكها في فيه فقال له النبي صلى الله عليه وسلم كخ كخ لا تحل لنا الصدقة
