Speech

Malik related to me that he heard that someone said to Luqman, "What has brought you to what we see?" meaning his high rank. Luqman said, "Truthful speech, fulfilling the trust, and leaving what does not concern me."

وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّهُ قِيلَ لِلُقْمَانَ مَا بَلَغَ بِكَ مَا نَرَى يُرِيدُونَ الْفَضْلَ ‏.‏ فَقَالَ لُقْمَانُ صِدْقُ الْحَدِيثِ وَأَدَاءُ الأَمَانَةِ وَتَرْكُ مَا لاَ يَعْنِينِي ‏.‏
