Dhikr of Allah is similar to water for fish

Shaykhul Islaam Ahmad ibn Taymeeyah 728AH said: الذكر للقلب مثل الماء للسمك, فكيف يكون حال السمك اذا فارق الماء “Remembrance of Allah as it relates to the heart is equivalent to water for fish. Therefore how is the fish’s conditoon when it is separated from water?” Source: Al-Waabilus Sayyib- Ibn Qayyim p.85

Do not debate with the ignorant

Abu ʿAbdillah Muhammad ibn Idris ash-Shafi’ee 204 AH (May Allah have mercy on him) said, ما جادلت عالما الا غلبته ، وما جادلت جاهلا الا غلبني “I have never debated with a knowledgeable person, except that I won the debate, and I have never debated with an ignorant person, except that I lost.”
