Hadith 5:595
'Amr narrated to us, from Ibn Jurayj, from 'Ata', who said: "If you give [charity] using the mudd of the Prophet, may Allah bless him and grant him peace, it suffices for you. And if you give [charity] using the mudd with which you provide food for your family, it suffices for you."
حدثنا عمرو عن بن جريج عن عطاء قال إذا أعطيت بمد النبي صلى الله عليه وسلم أجزى عنك وإن أعطيت بالمد الذي تقوت به أهلك أجزى عنك
