Mishkat al-Masabih 6 Zakat كتاب الزكاة 76

وَعَنْ عَطَاءِ بْنِ يَسَارٍ عَنْ رَجُلٍ مِنْ بَنِي أَسَدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ سَأَلَ مِنْكُمْ وَلَهُ أُوقِيَّةٌ أَوْ عَدْلُهَا فَقَدْ سَأَلَ إِلْحَافًا» . رَوَاهُ مَالك وَأَبُو دَاوُد وَالنَّسَائِيّ

‘Ata’ b. Yasar, on the authority of a man of the B. Asad, reported God’s messenger as saying, “If any of you begs when he has an Uqiya* or its equivalent, he has begged immoderately.” Malik, Abu DawQd and Nasa’i transmitted it. * The Uqiya (ounce) of the Arabs was forty dirhams.
