Muslim have always been encouraged to write their Wasiat.
As  the prophet s.a.w said : "it is not permissible for any Muslim who  has  something to will to stay for two nights without having his last Will  and Testament written and kept ready with him. (Sahih Al-Bukhari vol IV  p.1).
 Wasiat lets  the person to choose a trusted person as an Executor. A male testator is  empowered by Muslim law to appoint a guardian a person whom he trusts  the most. The assets and liabilities of the deceased fall under the  generic term "estate". If a Muslim dies intestate (without a wasiat), a beneficiary must take several steps before he can benefit from the inheritance.
Distribution  of the proceeds of an intestate estate may take one to two years or  longer. If there are obstacles, such as the failure of beneficiaries to  agree on the choice of administrators, or the inability of the  administrator to provide adequate sureties. Until all these legal  requirements are met, the estate of the deceased remains frozen.
  The existence of Faraid does not mean that a benefiaciary can obtain his entitlement immediately after the death of a person. Faraid exists in harmony with wasiat. The rights of heirs are protected under faraid  and yet a testator may still make provisions to benefit loved ones who  do not fall within the category of heirs in Islam such as adopted  children or non-Muslim parents or any charitable body and the like. With  a wasiat, he can still divide his assets according to Faraid.
