4- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ مَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الآخِرِ فَلا يَسْتَعْمِلَنَّ أَجِيراً حَتَّى يُعْلِمَهُ مَا أَجْرُهُ وَمَنِ اسْتَأْجَرَ أَجِيراً ثُمَّ حَبَسَهُ عَنِ الْجُمُعَةِ يَبُوءُ بِإِثْمِهِ وَإِنْ هُوَ لَمْ يَحْبِسْهُ اشْتَرَكَا فِي الأجْرِ.
4. Ali ibn Ibrahim has narrated from his father from Harun ibn Muslim from Mas’adah ibn Sadaqah who has said the following: “Abu ‘Abd Allah 
, has said, ‘Whoever believes in Allah and on Day of Judgment must not make a person work for him on hire until he knows how much his wages are, and if one hires a person and keeps him from Friday prayer, he is held responsible for his sin; and if he allows him to attend Friday prayer they will share the reward.’”
