When it comes to treatment of our parents, Allah does not accept a small effort, a mediocre effort, or even a good effort. When it comes to treatment of our parents, Allah has one word: Ihsan (perfection, excellence, the very best)!
There will come a time when filth will become acceptable. But no matter how acceptable and common it becomes in society, don’t forget that the filthy and the good and pure will never be equal in the sight of Allah.
Allah created us so that He could show us His love and mercy. If only we show a little gratitude and faith, then Allah Himself is appreciative towards His creation.
