Narrated Ibn Mas'ud (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Do not buy the fish that is in the water, for it involves uncertainty (risk)." [Reported by Ahmad who indicated that the correct view is that it is Mawquf (saying of a Companion, i.e. Ibn Mas'ud] .

Narrated Ibn 'Abbas (RA): Allah's Messenger ( صلی اللہ علیہ وسلم ) forbade the selling of a fruit till it becomes ripe, or the selling of fur which is (still) on the back (of an animal) or milk which is (still) in the udder. [Reported by at-Tabarani in al-Awsat. ad-Daraqutni also reported it] . Abu Dawud reported in al-Marasil as a saying of 'Ikrimah, and that is the strongest opinion. He also reported it Mawquf (as a saying of a Companion, i.e.) Ibn 'Abbas with a strong chain of narrators, and al-Baihaqi held it to the most correct narration.

Narrated Abu Hurairah (RA): The Prophet ( صلی اللہ علیہ وسلم ) forbade the sale of what is in the womb of a she-camel, and the semen that is in the body of a male-camel. [Reported by al-Bazzar and there is weakness in its Isnad (chain of narrators)] .

Narrated [Abu Hurairah (RA)] : Allah's Messenger ( صلی اللہ علیہ وسلم ) said: "Whoever accepts back what he sold to a Muslim, Allah will forgive his fault." [Reported by Abu Dawud and Ibn Majah. Ibn Hibban and al-Hakim graded it Sahih (authentic)] .
