Umar ibn al-Khattab advised Sa’d ibn Abi Waqqas saying :
"You are going to face something difficult,
& nothing can save you from it except the truth. Accustom yourself &
those who are with you to doing good, start everything with good, &
remember that for every good habit there is a means to develop it. The means of
developing good is patience. If you are patient in bearing everything that
befalls you or happens to you, you will gain the fear [taqwa] of Allaah.”
