Muwatta Malik, Book 20, Hadith 856 (In-Book) ⓘ

Yahya related to me from Malik from Hisham ibn Urwa that his father used to say to his sons, "My sons, let none of you sacrifice any animal which he would be ashamed to sacrifice for a noble woman, for surely Allah is the noblest of noble ones, and the most deserving of those for whom things are chosen."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يَقُولُ لِبَنِيهِ يَا بَنِيَّ لاَ يُهْدِيَنَّ أَحَدُكُمْ مِنَ الْبُدْنِ شَيْئًا يَسْتَحْيِي أَنْ يُهْدِيَهُ لِكَرِيمِهِ فَإِنَّ اللَّهَ أَكْرَمُ الْكُرَمَاءِ وَأَحَقُّ مَنِ اخْتِيرَ لَهُ ‏.‏
