Muwatta Malik, Book 38, Hadith 1468 (In-Book)

Malik related to me from Yahya ibn Said and somebody else from al-Hasan ibn Abi al-Hasan al-Basri and from Muhammad ibn Sirin that a man in the time of the Messenger of Allah, may Allah bless him and grant him peace, freed six of his slaves while he was dying. The Messenger of Allah, may Allah bless him and grant him peace, drew lots between them and freed a third of those slaves. Malik added that he had heard that the man did not have any property other than them.

حَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، وَعَنْ غَيْرِ، وَاحِدٍ، عَنِ الْحَسَنِ بْنِ أَبِي الْحَسَنِ الْبَصْرِيِّ، وَعَنْ مُحَمَّدِ بْنِ سِيرِينَ، أَنَّ رَجُلاً، فِي زَمَانِ رَسُولِ اللَّهِ صلى الله عليه وسلم أَعْتَقَ عَبِيدًا لَهُ سِتَّةً عِنْدَ مَوْتِهِ فَأَسْهَمَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَهُمْ فَأَعْتَقَ ثُلُثَ تِلْكَ الْعَبِيدِ ‏.‏ قَالَ مَالِكٌ وَبَلَغَنِي أَنَّهُ لَمْ يَكُنْ لِذَلِكَ الرَّجُلِ مَالٌ غَيْرُهُمْ ‏.‏
