In Islam, fatwa is considered a serious matter because of its clear impact on the organization of the life of the believers. In fact, Islam did not make fatwa rigid rather it is flexible to include developments in society. Also, changes of the Fatwa are permissible should certain justifications calls for it, such as: a change of customs and habits, or a change of interests, or the diversity of means and so on. That being said, this change is not arbitrary, it is governed by controls and conditions, including not contradicting religious texts and taking into account scientific progress in the various walks of life. In addition, the change must come from a diligent scholar, who may be an individual or a group, and who has the ability to balance the pros and cons. It is also required that the change must be warranted, and it must not be compromised by nepotism and/or favoritism
