3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-‘Abbas ibn Ma’ruf from abu Shu’ayb al-Muhamiliy al- Ri fa Ay who has narrated the following: “I once asked abu ‘Abd Allah , about the case of a man who forms a contract with another man. It requires him to dig a well of ten heights of a man deep for ten dirhams of which he digs one height and could not do the rest. Abu ‘Abd Allah , has said, ‘He deserves one part out of fifty- five parts of a ten dirhams.’”
