If you wish to check how much you love Allah, then see how much your heart loves the Quran, and you will know the answer.
Ibn Qayyim Al-JawziyyaHow strange! You lose a little from you and you cry. And your whole life is wasting and you're laughing
Ibn Qayyim Al-JawziyyaEverything that is loved, if it is not loved for His sake then this love is nothing but distress and punishment. Every action that is not performed for His sake then it is wasted and severed. Every heart that does not reach Him is wretched; veiled from achieving its success and happiness.
Ibn Qayyim Al-JawziyyaThe heart becomes sick, as the body becomes sick, and its remedy is al-Tawbah (repentance) and protection [from transgression]. It becomes rusty as a mirror becomes rusty, and its clarity is obtained by remembrance. It becomes naked as the body becomes naked, and its beautification is al-Taqwa. It becomes hungry and thirsty as the body becomes hungry, and its food and drink are knowledge, love, dependence, repentance and servitude.
Ibn Qayyim Al-Jawziyya
