[Machine] In the mosque of the Messenger of Allah ﷺ, there was a man from the Banu 'Udhrah tribe known as Abu al-Mathkur. He had a Coptic slave whom he emancipated for a ransom. Then, he experienced some financial difficulty, so the Messenger of Allah ﷺ said to him, "If any of you is in need, let him start with himself." He then sold him to Nu'aym ibn 'Abdullah, the brother of Banu 'Adi ibn Ka'b, for eight hundred dinars. He benefited from this wealth and became one of the mujahideen and the knowledgeable people of the people of Makkah who sought guidance in their affairs and acted according to the advice of its owner in the best manner as long as Allah willed, and he spent from it as he pleased.  

كَانَ فِي مَسْجِدِ رَسُولِ اللهِ ﷺ رَجُلٌ مِنْ بَنِي عُذْرَةَ يُقَالُ لَهُ أَبُو الْمَذْكُورِ وَكَانَ لَهُ عَبْدٌ قِبْطِيٌّ فَأَعْتَقَهُ عَنْ دُبُرٍ مِنْهُ ثُمَّ احْتَاجَ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ إِذَا كَانَ أَحَدُكُمْ ذَا حَاجَةٍ فَلْيَبْدَأْ بِنَفْسِهِ قَالَ فَبَاعَهُ مِنْ نُعَيْمِ بْنِ عَبْدِ اللهِ أَخِي بَنِي عَدِيِّ بْنِ كَعْبٍ بِثَمَانِمِائَةٍ فَانْتَفَعَ بِهَا فَكَانَ مُجَاهِدٌ وَفُقَهَاءُ أَهْلِ مَكَّةَ يَرَوْنَ التَّدْبِيرَ وَصِيَّةً صَاحِبُهَا فِيهَا بِالْخِيَارِ مَا عَاشَ يُمْضِي فِيهَا مَا شَاءَ وَيَرُدُّ مِنْهَا مَا شَاءَ
