>>>Women's witness is half of Man's>>> This applies only in financial transactions related disputes.
This is the actual verse of the Quran Believers, when you make a deal for a loan for a prescribed period of time, write down the agreement. A scribe should write down the agreement between you, with justice. The scribe should not refuse to write it down, as God gave him the knowledge of writing. So he must write it down. The debtor should dictate the writing and [while doing so,] he must fear God, his Lord [and dictate it justly] and not reduce any part of the amount. If the debtor is not of a sound mind or is weak or is in any other way incapacitated to dictate the agreement, then his guardian may dictate [the terms on his behalf] with justice. Make two of your men a witness on this agreement. In case two men are not available, then a man and two women. Such witnesses as you choose. [Two women in place of one man have been advised, so] that if one of them errs, the other may remind her. The witnesses should not refuse when they are called to testify..
