أَخْبَرَنَا الْحُسَيْنُ بْنُ إِسْحَاقَ، قَالَ أَنْبَأَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا سَعْدُ بْنُ أَوْسٍ، قَالَ حَدَّثَنِي بِلاَلُ بْنُ يَحْيَى، أَنَّ شُتَيْرَ بْنَ شَكَلٍ، أَخْبَرَهُ عَنْ أَبِيهِ، شَكَلِ بْنِ حُمَيْدٍ قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فَقُلْتُ يَا نَبِيَّ اللَّهِ عَلِّمْنِي تَعَوُّذًا أَتَعَوَّذُ بِهِ فَأَخَذَ بِيَدِي ثُمَّ قَالَ " قُلْ أَعُوذُ بِكَ مِنْ شَرِّ سَمْعِي وَشَرِّ بَصَرِي وَشَرِّ لِسَانِي وَشَرِّ قَلْبِي وَشَرِّ مَنِيِّي " . قَالَ حَتَّى حَفِظْتُهَا قَالَ سَعْدٌ وَالْمَنِيُّ مَاؤُهُ . خَالَفَهُ وَكِيعٌ فِي لَفْظِهِ .
It was narrated that Shakal bin Humaid said:"I came to the Prophet [SAW] and said: 'O Prophet of Allah, teach me words by which I may seek refuge (with Allah).' He took me by the hand then said: 'Say: A'udhu bika min sharri sam'i, wa sharri basari, wa sharri lisani, wa sharri qalbi, wa sharri mani (I seek refuge in You from the evil of my hearing, the evil of my seeing, the evil of my tongue, the evil of my heart, and the evil of my sperm),' until I had memorized it." Waki' contradicted him in the wordings
