عَنْ أَبِي الدَّرْدَاءِ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ سَمِعَ مِنْ رَجُلٍ حَدِيثًا لَا يَشْتَهِي أَنْ يُذْكَرَ عَنْهُ فَهُوَ أَمَانَةٌ وَإِنْ لَمْ يَسْتَكْتِمْهُ
Sayyiduna Abu Darda (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever hears something from a man, and that man does not want that thing to be mentioned with reference to him, then that thing is a trust, even if the speaker does not instruct to keep it secret.
