"You are going to face something difficult..."

  
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.”
