Keep doing the right thing despite the trouble, difficulty and betrayal. One day, the Almighty will connect the dots for you and it'll all make sense. Till then, press on and bear patience.
You can’t possibly see & correct your own shortcomings if you’re focused on criticizing others. Remember, you’re accountable for all your actions. The Almighty will ask you about what you’ve done, not about what others have done. Save yourself by focusing on yourself.
