my father was one who remembered [Allah] a lot. When I walked with him, he would be in constant remembrance of Allah. When I ate food with him, he would be in constant remembrance of Allah. He would be speaking to people but that did not preoccupy him from remembering Allah. I would notice his tongue stick to his palate, uttering, 'There is no god but Allah.' He used to gather us and command us to remember Allah until the sun rose, and he would command whoever could read from among us to read the Qur'an, and whoever could not, to remember Allah.'
