The meaning of taqwa

“As for Taqwa, its reality is to act in accordance with the commands of Allaah, out of faith and in expectance of the reward. This includes [complying with] His Orders and  [abstaining  from]  His  Prohibitions.  Therefore,  a person  does what  Allah  has  ordered  out  of  faith  in  the One  giving  the  order,  and out of  belief  in  His  Promise. Also,  they  refrain from  what  Allaah  has prohibited, out of  faith  in  the  One  prohibiting,and  out  of  fear  of  His promise of punishment.

— Ibn Al-Qayyim | Zaad Al-Muhaajir(pg. 10)
