Al-Adab Al-Mufrad, Book 14, Hadith 288 (English) ⓘ

'Abdullah ibn 'Amr said, "There are four qualities such that if you were to be given them, you will not be harmed even if the world were to be taken away from you. They are: good character, restraint in food, truthful words, and upholding a trust."

حَدَّثَنَا عَبْدُ اللهِ بْنُ صَالِحٍ قَالَ‏:‏ حَدَّثَنِي مُوسَى بْنُ عَلِيٍّ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو قَالَ‏:‏ أَرْبَعُ خِلاَلٍ إِذَا أُعْطِيتَهُنَّ فَلاَ يَضُرُّكَ مَا عُزِلَ عَنْكَ مِنَ الدُّنْيَا‏:‏ حُسْنُ خَلِيقَةٍ، وَعَفَافُ طُعْمَةٍ، وَصِدْقُ حَدِيثٍ، وَحِفْظُ أَمَانَةٍ‏.‏
