Hadith 790:20
Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Yazid al-Rishk, who said: I heard Mutarrif narrating from 'Imran ibn Husayn, from the Prophet, may Allah bless him and grant him peace, that he was asked, or it was said to him: "Are the people of the Fire known from the people of the Paradise?" He said: "Yes." He said: "Then why do the workers work?" He said: "Each one works for what he was created for," or "for what was made easy for him."
حدثنا محمد بن جعفر، حدثنا شعبة، عن يزيد الرشك قال: سمعت مطرفا يحدث: عن عمران بن حصين، عن النبي صلى الله عليه وسلم أنه سئل، أو قيل له، أيعرف أهل النار من أهل الجنة؟ فقال: " نعم ". قال: فلم يعمل العاملون؟ قال: " يعمل كل لما خلق له " أو " لما يسر له "
