[Machine] Abdullah said to him, "What is wrong with you, O Umair? I want to free you, for I heard the Messenger of Allah ﷺ saying, 'Whoever frees a slave, his wealth belongs to the one who freed him.'" We were also informed by Al-Qasim ibn Abdur Rahman that Ibn Mas'ud said this to Umair, even though it is possible that he was sent with this message, and there is strength in the narration of Abdul Ala. Ath-Thawri also narrated it from Abu Khalid, from Imran ibn Umair, from his father, that Ibn Mas'ud freed his father, Umair, and then he said, "Indeed, your wealth is for me, and then he left it."  

قَالَ لَهُ عَبْدُ اللهِ مَا مَالُكَ يَا عُمَيْرُ فَإِنِّي أُرِيدُ أَنْ أُعْتِقَكَ؟ إِنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ أَعْتَقَ عَبْدًا فَمَالُهُ لِلَّذِي أَعْتَقَ وَرُوِّينَا عَنِ الْقَاسِمِ بْنِ عَبْدِ الرَّحْمَنِ أَنَّ ابْنَ مَسْعُودٍ قَالَ ذَلِكَ لِعُمَيْرٍ وَهُوَ وَإِنْ كَانَ مُرْسَلًا فَفِيهِ قُوَّةٌ لِرِوَايَةِ عَبْدِ الْأَعْلَى وَرَوَاهُ الثَّوْرِيُّ عَنْ أَبِي خَالِدٍ عَنْ عِمْرَانَ بْنِ عُمَيْرٍ عَنْ أَبِيهِ أَنَّ ابْنَ مَسْعُودٍ أَعْتَقَ أَبَاهُ عُمَيْرًا ثُمَّ قَالَ أَمَا إنَّ مَالَكَ لِي ثُمَّ تَرَكَهُ
