Sunan Ibn Majah Book 16, Hadith 9
“I heard 'Utbah bin Nuddar say: 'We were with the Messenger of Allah (ﷺ) and he recited Ta-Sin. When he reached the story of Musa, he said: 'Musa (A.S) hired himself out for eight years, or ten, in return for his chastity and food in his stomach.' ”
“Give the worker his wages before his sweat dries.”
I heard Abu Hurairah say: “I grew up an orphan, and I emigrated as a poor man, and I was hired by the daughter of Ghazwan in return for food and a turn riding the camel. I would gather firewood for them when they stopped to camp and urge their camels along for them by singing when they rode. Praise is to Allah (SWT) who has caused His religion to prevail and has made Abu Hurairah an Imam.”
