Abu Sa’id on Silence: By silence you will overcome the Devil

‘Aqil ibn Mudrik reported: A man said to Abu Sa’id al-Khudri, may Allah be pleased with him, “Advise me.” Abu Sa’id said, “You must be silent except in the truth, for by it you will defeat Satan.”

عن عقيل بن مدرك أَنَّ رَجُلًا قَالَ لِأَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ أَوْصِنِي قَالَ عَلَيْكَ بِالصَّمْتِ إِلَّا فِي حَقٍّ فَإِنَّكَ بِهِ تَغْلِبُ الشَّيْطَانَ
