5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Safwan from Aban from ‘Abd al- Rahman ibn abu ‘Abd Allah who has said the following
“Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, prohibited al- Muhaqalah and al-Muzabanah .’ I then asked, ‘What are they?’ He (the Imam) said, ‘It is selling what a palm tree has just conceived in exchange for dates and green plantation for wheat.’”
