Love

If you have to fulfil a duty for someone you love, then it’s no burden for you because the love you have for them will lift it. If there is no love present, it feels tiresome and burdensome. That’s why the Prophet ﷺ stood all night in prayer even though it caused him pain because he did it out of love for Allah ﷻ.
— Shaykh Ahmad Saad al Azhari
