Muwatta Imam Malik Book of Sadaqa, Hadith 8
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ said from the mimbar when mentioning sadaqa and refraining from asking, "The upper hand is better than the lower hand. The upper hand is the one which expends, and the lower one is the one which asks."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ - وَهُوَ عَلَى الْمِنْبَرِ وَهُوَ يَذْكُرُ الصَّدَقَةَ وَالتَّعَفُّفَ عَنِ الْمَسْأَلَةِ - " الْيَدُ الْعُلْيَا خَيْرٌ مِنَ الْيَدِ السُّفْلَى وَالْيَدُ الْعُلْيَا هِيَ الْمُنْفِقَةُ وَالسُّفْلَى هِيَ السَّائِلَةُ " .
