Imam Ibnul Qayyim (rahimahullaah) states in Al Fawaa-id that Ibn Sad (rahimahullaah) mentions in
At Tabaqaat about Umar Bin Abdul Azeez (rahimahullaah) that:
Whenever he delivered a khutbah on the mimbar, and feared being amazed by himself; he would terminate it (i.e. the khutbah). And whenever he wrote a letter and feared amazement by way of it; he would tear it.
And he would say: O Allaah! I seek refuge in you from the evil of my nafs.
Al Fawaa-id of Imaam Ibnul Qayyim (rahimahullaah) (page: 225) هَلْ جَزَاء الْإِحْسَانِ إِلَّا الْإِحْسَانُ؟
Is there any reward for good other than good?
[ar-Rahman: 60] * Official Member of the Poet Crew * O Allah, Lord of Jibril, Mika'il and Israfil, Creator of the heavens and the earth, Knower of the unseen and the seen, You will judge between Your servants concerning that wherein they differ. Guide me with regard to that wherein there is dispute concerning the truth by Your leave, for You guide whomsoever You will to the straight path.
Oh Allah, I seek refuge in You lest I misguide others, or I am misguided by others, lest I cause others to err or I am caused to err, lest I abuse others or be abused, and lest I behave foolishly or meet with the foolishness of others.
