Judgements

Malik related to me from Yahya ibn Said from Said ibn al-Musayyab that Umar ibn al-Khattab said while he was leaning his back against the Kaba, "Whoever takes a stray is astray."

وَحَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، قَالَ وَهُوَ مُسْنِدٌ ظَهْرَهُ إِلَى الْكَعْبَةِ مَنْ أَخَذَ ضَالَّةً فَهُوَ ضَالٌّ ‏.‏
