Hadith 5:879
Ibn ‘Uyaynah narrated to us, from Zayd ibn Aslam, from ‘Ata’ ibn Yasar, who attributed it to the Prophet, may Allah bless him and grant him peace: "Whoever asks while he possesses an *uqiyah* (a weight of silver) or its equivalent, he is asking the people persistently."
حدثنا بن عيينة عن زيد بن أسلم عن عطاء بن يسار يبلغ به النبي صلى الله عليه وسلم من سأل وله اوقية أو عدلها فهو يسأل الناس إلحافا
