Shumayt bin Ajlan (may Allah have mercy on him), while describing the traits of worldly people, says:

"He is always a worshiper of his stomach and devoid of intellectual wisdom (sagacity). Except for fulfilling the desires of his stomach and private parts, he remains unconcerned about all other obligations. Every moment he thinks only about when it will be morning so that he can engage in eating, drinking, and other amusements, and when it will be night so that he can go to his bedroom and rest. He is a dead corpse by night and a useless person by day."

[Al-Zuhd by Imam Ahmad]
