nine uqiyas, one in each year; therefore assist me." ʿÁyesha replied, "If thy masters desire, I will count it over to them in one counting and set thee free; but the right to inherit thy property must remain with me." Then Barirah went to her masters, but they refused, unless the right to inherit her property remained with them. Then the Apostle of God said, "Take her and set her free." Afterwards the Apostle of God stood up amongst the people and magnified God and praised Him. Then after that he said, "What will be the condition of those men who make stipulations which are not in the Book of God! Whatever stipulation is not in the Book of God is null and void, even though there be one hundred of them. And the commands of God are more worthy (to be obeyed), and the stipulations of God are more binding. And verily the right to inherit is only for the one who emancipates."'—Muslim, Al Bukhárí.
