Narrated Suhaib (RA): The Prophet ( صلی اللہ علیہ وسلم ) said: "There are three things which contain blessings: A business transaction in which payment is agreed on a fixed later time, al-Muqaradah (speculative partnership), and mixing wheat and barley for one's household use but not for sale." [Reported by Ibn Majah through a Da'if (weak) chain of narrators] .

Narrated al-Hakim bin Hazim (RA): He used to make a condition on the man to whom he gave his property in al-Muqaradah (to trade with, and the profit being shared between them), that: "You should not trade with my property in living beings, and do not transport it by sea, and do not settle with it at the bottom of a river-bed; and if you do any of the aforesaid acts you should then guarantee my property." [ad-Daraqutni reported it and its narrators are reliable (thiqah)] . Malik said in al-Muwatta' from al-'Ala bin 'Abdur-Rahman bin Ya'qub from his father on the authority of his grandfather that he traded with some property belonging to 'Uthman (RA) so that the profit would be divided between them. [This hadith is Mawquf (saying of a Companion) Sahih (authentic)] .
