The worst type of love is unrequited love: when you love somebody and they don’t love you – there is nothing worst than that in the world, unrequited love. And obviously the worst type of unrequited love is with God, because we want the Love of God. ~ Shaykh Hamza Yusuf.
“Allahumma inni asaluka hubbak(a), wa hubba may yuhibuk(a), wa l-amala ‘lladhi yuballighuni hubbak(a)”
O Allah! I beg of You Your love and the love of those who love You and I ask of You such deeds which will bring me Your love. (Tirmidhi)
