Sunan Ibn Majah Book 34, Hadith 16
the Messenger of Allah (saas) said: "Seek refuge with Allah from poverty, insufficiency and humiliation, and from wronging (others) and being wronged.'"
"I noticed that the Messenger of Allah (saas) was missing from his bed one night, so I went looking for him, and my hand touched the soles of his feet; he was in the Masjid with his feet upright (prostrating), and he was saying: 'Allahumma inni a'udhu biridaka min sakhatika wa bimu'afatika 'an 'uqubatika, wa a'udhu bika minka, la uhsi thana'an 'alayka, Anta kama athnayta 'ala nafsika (O Allah, I seek refuge in Your pleasure from Your wrath, and in Your forgiveness from Your punishment. I seek refuge in You from You. I cannot praise You enough; You are as You have praised Yourself).'"
the Messenger of Allah said: "Ask Allah for beneficial knowledge and seek refuge with Allah from knowledge that is of no benefit."
