Wrong

Its like when you pour a jug of orange juice into a car's oil tank so that it can move, the car explodes.

Why?

Because its the wrong mixture fr the engine.

Same goes to the heart.

The heart breaks when the wrong love is put into it. It should have been Allah's love and yet we look for human's love which is totally temporary and full of imperfections. And we break.

Because we are humans. Humans are weak.
