question #2 Sahih al-Bukhari 2822, Book 56, Hadith 38 : Why is it important to seek refuge from cowardice and a bad stage of old life in Islamic teachings?

Sa`d used to teach his sons the following words as a teacher teaches his students the skill of writing
and used to say that Allah’s Messenger (ﷺ) used to seek Refuge with Allah from them (i.e. the evils) at the
end of every prayer. The words are:
‘O Allah! I seek refuge with You from cowardice, and seek refuge with You from being brought back
to a bad stage of old life and seek refuge with You from the afflictions of the world, and seek refuge
with You from the punishments in the grave.’
