Ibn Taymiyyah said: "This (enjoining good and forbidding evil) is a duty that the entire Ummah is obliged to fulfil. It is what the Ulama know as an obligation of collective responsibility, if a group in society undertook to discharge it, the other members of this society are absolved from it. The entire Ummah is commissioned to undertake it, but if a group therein was responsible for discharging it, the rest of society is no longer obliged to undertake it."

Writing a will is a religious obligation on every capable Muslim. It protects against many problems and conflicts that could arise after a person’s death. This obligation is more emphasized in the West: Failing to write a well-founded will may result in the distribution of one’s estate in discord with the Islamic law, and may lead to losses for some of the rightful inheritors.
