كتاب صفة النبى صلى الله عليه وسلم

The Description of the Prophet, may Allah Bless Him and Grant Him Peace

Yahya related to me from Malik from Zayd ibn Aslam from Ibn Bujayd (formerly al-Ansari) from his grandmother that the Messenger of Allah, may Allah bless him and grant him peace, said, "Give to the very poor, if only a roasted hoof."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنِ ابْنِ بُجَيْدٍ الأَنْصَارِيِّ، ثُمَّ الْحَارِثِيِّ عَنْ جَدَّتِهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ رُدُّوا الْمِسْكِينَ وَلَوْ بِظِلْفٍ مُحْرَقٍ ‏"‏ ‏.‏
