Sunan an-Nasa'i, Book 48, Hadith 184 (In-Book) ⓘ

It was narrated from Abu Al-Ahwas that his father said: "I was sitting with the Messenger of Allah [SAW] and he saw that I was dressed in scruffy clothes. He said: 'Do you have any wealth?' I said: 'Yes, O Messenger of Allah, all kinds of wealth.' He said: 'If Allah gives you wealth then let its effect be seen on you.'"

أَخْبَرَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ قَالَ حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ، قَالَ حَدَّثَنَا أَبُو إِسْحَاقَ، عَنْ أَبِي الأَحْوَصِ، عَنْ أَبِيهِ، قَالَ كُنْتُ جَالِسًا عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَآنِي رَثَّ الثِّيَابِ فَقَالَ ‏"‏ أَلَكَ مَالٌ ‏"‏ ‏.‏ قُلْتُ نَعَمْ يَا رَسُولَ اللَّهِ مِنْ كُلِّ الْمَالِ ‏.‏ قَالَ ‏"‏ فَإِذَا آتَاكَ اللَّهُ مَالاً فَلْيُرَ أَثَرُهُ عَلَيْكَ ‏"‏ ‏.‏
