Sometimes naseeb (fate) can come in the form of separation. In the form of loss; loss of a loved one, loss of wealth, loss of a job or loss of something that was dear to you.
Remind yourself that even this was written. Out of His Wisdom, He knew this would enlighten you and guide you. To bring you back to Him.
It's not easy to see it that way because separation causes our hearts to break. But it's in that moment, when our hearts are in pieces, that the Light of Allah can enter and fill the gaps.
That heart of yours was made to heal. If you allow it. And it will be stronger than before.
Better than before. Naseeb does that.
Don't let your tests make you lose hope in the Mercy of Allah. Let it soften you and bring you back to Him.
