حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الأَنْبَارِيُّ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، - رضى الله عنه - قَالَ مَنْ مَلَكَ ذَا رَحِمٍ مَحْرَمٍ فَهُوَ حُرٌّ .
Narrated Umar ibn al-Khattab: Qatadah reported Umar ibn al-Khattab (may Allah be pleased with him) as saying: If anyone gets possession of a relative who is within the prohibited degrees, that person becomes free
