3655 - وَ رَوَى مُحَمَّدُ بْنُ خَالِدٍ اَلْبَرْقِيُّ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ قَالَ : سَأَلْتُهُ عَنِ اَلْإِجَارَةِ فَقَالَ "صَالِحٌ لاَ بَأْسَ بِهَا إِذَا نَصَحَ قَدْرَ طَاقَتِهِ قَدْ آجَرَ نَفْسَهُ مُوسَى بْنُ عِمْرَانَ عَلَيْهِ اَلسَّلاَمُ وَ اِشْتَرَطَ قَالَ إِنْ شِئْتُ ثَمَانِياً وَ إِنْ شِئْتُ عَشْراً فَأَنْزَلَ اَللَّهُ تَعَالَى فِيهِ عَلىٰ أَنْ تَأْجُرَنِي ثَمٰانِيَ حِجَجٍ فَإِنْ أَتْمَمْتَ عَشْراً فَمِنْ عِنْدِكَ ".
Hadith.3655 - Muhammad bin Khalid Al-Barqi narrated from Muhammad bin Sinan, who narrated from Abu Al-Hasan 
that he said: I asked him about hiring (employment).
Imam 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 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)
