We can do many Good Deeds but we do not protect them, we might do something that ruined them, very dangerously. We work extremely hard, we pray, we fast, we give in charge, we do so many things. So does not make any sense to ruin all that or to come on the day of judgment and find everything has been destroyed.
So the doing the hasanat is excellent but protecting them is the most important thing in our life. So what are the actions that can destroy all my good deeds.
Number one, Shirk associating partners with Allah (S.W.T)
