Imam Baqir ع said “I would only fear death if it came upon me while committing an act of disobedience.” 

Kitab al Irshad by Sheikh al Mufid 

Let us be more aware of how we live our lives on a day to day basis and let us ponder on death and what state we will meet our Creator, so that death does not catch us all of a sudden while we are unprepared or while committing disobedience to Him.
