حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ أَبِي الأَحْوَصِ، عَنْ أَبِيهِ، قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فِي ثَوْبٍ دُونٍ فَقَالَ ‏"‏ أَلَكَ مَالٌ ‏"‏ ‏.‏ قَالَ نَعَمْ ‏.‏ قَالَ ‏"‏ مِنْ أَىِّ الْمَالِ ‏"‏ ‏.‏ قَالَ قَدْ أَتَانِيَ اللَّهُ مِنَ الإِبِلِ وَالْغَنَمِ وَالْخَيْلِ وَالرَّقِيقِ ‏.‏ قَالَ ‏"‏ فَإِذَا أَتَاكَ اللَّهُ مَالاً فَلْيُرَ أَثَرُ نِعْمَةِ اللَّهِ عَلَيْكَ وَكَرَامَتِهِ ‏"‏ ‏.‏

Abu al-Ahwas quoted his father saying: I came to the Prophet (PBUH) wearing a poor garment and he said (to me): Have you any property? He replied: Yes. He asked: What kind is it? He said: Allah has given me camels. Sheep, horses and slaves. He then said: When Allah gives you property, let the mark of Allah's favour and honour to you be seen. Translation Not Available
