عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ((أَرْبَعٌ إِذَا كُنَّ فِيكَ فَلَا عَلَيْكَ مَا فَاتَكَ مِنَ الدُّنْيَا حِفْظُ أَمَانَةٍ وَصِدْقُ حَدِيثٍ وَحُسْنُ خَلِيقَةٍ وَعِفَّةٌ فِي طَعْمَةٍ))
It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him and his family) said: There are four virtues; if you possess them, you should not grieve over anything lost from the world: safeguarding trust, speaking the truth, good character, and chastity in food (i.e., earning lawful sustenance sufficient for your needs).
