1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Sulayman ibn Ja’far al-Ja’fariy who has said the following: “I once was with al-Rida’ , because of a certain work and I wanted to leave for my home but he (the Imam) said, ‘Come with me and stay for the night with me/ I went with him (the Imam), he entered in his house with al-Mu‘attib and looked at his slaves who worked with clay, in the animal barn and other things and with them there was a black man who was not one of them. He (the Imam) asked, ‘Who is this man with you?’ They replied, ‘He is helping us and we will give him something.’ He (the Imam) then asked, ‘Have you determined how much you must pay him?’ They replied, ‘No, because he will agree with whatever we will give him.’ He (the Imam) turned upon them using a whip, expressing intense anger. I then said, ‘I pray to Allah to keep my soul in service for your cause, please do not take it upon yourself.’ He (the Imam) said, ‘I have prohibited them many times from allowing anyone to work with them without determining his wages. I know that there is no one who works for you in anything without determining his wages; then you pay him three times more than what his work is worth for, he still thinks that you have paid him less than his wages; but if you determine his wages first, then pay his wages he will be grateful to you for keeping your promise and if you increase even by one grain he will recognize it as your favor and see that you have paid him extra.’”
