Hadith record

Hadith.3655 - Muhammad bin Khalid Al-Barqi narrated from Muhammad bin Sinan, who narrated from Abu Al-Hasan (as) that he said: I asked him about hiring (employment). Imam (as) said: 'It is permissible and there is no harm in it as long as one does it sincerely and to the best of his ability. Indeed, Musa bin Imran (as) hired himself out and stipulated: "If you wish, for eight years, and if you wish, for ten years." Then Allah (swt), the Exalted, revealed regarding him: That you serve me for eight years, but if you complete ten, it will be of your own accord.'' (Surah Al-Qasas 28:27)
