The Prophet used to seek refuge with Allah from cowardice, miserliness, the tribulation of the heart and the torment of the grave.
Sunan an-Nasa'i Book 50, Hadith 16
← Previous Hadith The Prophet used to seek refuge (with Allah) from four things: From knowledge that is of no benefit, from a heart that does not feel humble, from a supplication that is not heard, and a soul that is never satisfied.

Sunan an-Nasa'i Book 50, Hadith 15 Next Hadith → "I came to the Prophet and said: 'O Prophet of Allah, teach me words by means of which I may seek refuge with Allah.' He took me by the hand and said: 'Say: A'udhu bika min sharri sam'i, wa sharri basari, wa sharri lisani, wa sharri qalbi, wa sharri mani (I seek refuge with 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).'"
