Muwatta Imam Malik Book of Hair, Hadith 12

Yahya related to me from Malik from Summayy, the mawla of Abu Bakr from al-Qa'qa ibn Hakim that Kab al-Ahbar said, "Had it not been for some words which I said, the jews would have made me into a donkey." Someone asked him what they were. He said, "I seek refuge with the immense Face of Allah - there is nothing greater than it - and with the complete words of Allah which neither the good person nor the corrupt can exceed and with all the most beautiful names of Allah, what I know of them and what I do not know, from the evil of what He has created and originated and multiplied."
Audhu bi wajhi'llahi l-adheem aladhee laysa shay'un adham minh, wa bi kalimati'llahi't-tammati, alatee la yujawizu hunna barra wa la fajir, wa bi asma'illahi'l-husna kulliha ma alamtu minha wa ma lam alam, min sharri ma khalaqa wa bara'a wa dhara'a.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سُمَىٍّ، مَوْلَى أَبِي بَكْرٍ عَنِ الْقَعْقَاعِ بْنِ حَكِيمٍ، أَنَّ كَعْبَ الأَحْبَارِ، قَالَ لَوْلاَ كَلِمَاتٌ أَقُولُهُنَّ لَجَعَلَتْنِي يَهُودُ حِمَارًا . فَقِيلَ لَهُ وَمَا هُنَّ فَقَالَ أَعُوذُ بِوَجْهِ اللَّهِ الْعَظِيمِ الَّذِي لَيْسَ شَىْءٌ أَعْظَمَ مِنْهُ وَبِكَلِمَاتِ اللَّهِ التَّامَّاتِ الَّتِي لاَ يُجَاوِزُهُنَّ بَرٌّ وَلاَ فَاجِرٌ وَبِأَسْمَاءِ اللَّهِ الْحُسْنَى كُلِّهَا مَا عَلِمْتُ مِنْهَا وَمَا لَمْ أَعْلَمْ مِنْ شَرِّ مَا خَلَقَ وَبَرَأَ وَذَرَأَ .
