I heard Shaykul-Islaam Ibn Taymiyyah, may Allaah (Azza Wa Jall) sanctify his soul, say, 'Remembrance to the heart is like water to fish. What will be the state of the fish if it becomes seperated from the water?'

I once attended Fajr prayer with Shaykhul-Islaam Ibn Taymiyyah, he then sat and remembered Allaah (Azza Wa Jall) until it was nearly midday. He then turned around and said to me, "This is my early morning meal, if I do not take this breakfast, my strength will drop."

 

Ibn al-Qayyim says of Ibn Taymiyyah's remembrance of his Lord ( Al-Waabil as-Sayyib of Ibn al-Qayyim, pg. 60, Daar al-Bayaan)
