If you are looking for happiness in this world (dunya), you're in the wrong place.
Before anything can break your heart, it must first own your heart. Stop handing your heart to dunya-it'll stop breaking it.
In dunya, the image is always better than the reality. In Jennah, the Reality is better than any image ever could be.
Don't expect your spouse to be perfect. He/she is only the dunya version of themselves. Their 'perfect' version is saved for jennah.
Sometimes we make duaa for a door of dunya. When it doesn't open, we cry. Not realizing that Allah has instead opened a door of jennah for us.
