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.
