Hadith 58:3
Malik related to me from Zayd ibn Aslam that the Messenger of Allah, may Allah bless him and grant him peace, said, "Give to a beggar even if he comes on a horse."
وَحَدَّثَنِي مَالِكٌ، عَنْ زَيْدِ بْنِ أَسْلَمَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أَعْطُوا السَّائِلَ وَإِنْ جَاءَ عَلَى فَرَسٍ "
