“Imaam ibn Al Qayyim—may Allah have mercy upon him—said:

He went to his Shaykh—Shaykh of Islam ibn Taymiyyah—because he wanted to speak to him about something, or to take knowledge from him. So he found him siting remembering Allah. He was too afraid to speak to him until he finished from the remembrance of Allah. Then he turned to him and said: How long have you been here? He said: Since such and such a time and I am waiting. Thus the Shaykh (Ibn Taymiyyah) may Allah have mercy upon him said: ‘This is my breakfast, if I do not take my breakfast, I would not have strength to work that day’.”
