In Preparation for Death

Before death, try your best to fulfil the obligations, which are upon you in regard to the creatures as well as the Creator.

Return to the owners whatever has been given to you as a trust or write it down in your will so that the executor of your will shall return the trust to its rightful owner.
 
In Islam, you are allowed to dispose up to one-third of your estate for whomsoever or whatever cause you like. As for the two thirds, it must be distributed among your heirs according to the shares allocated for them in the shari’ah.
 
Make a will in writing or verbally about those religious obligations which you could not fulfil by yourself and which cannot be done on your behalf by others except after your death: the qadha prayers, fasting and pilgrimage (hajj), etc. You should specify the amount from the one-third of your estate to be used to hire people to do such deeds. If you cannot afford this, then you may request your heirs to do unfulfilled rituals on your behalf voluntarily or pay someone else to do so.
 
It is also recommended, if your financial circumstances allow you, to include your deserving relations in the one-third of your estate.
 
It is recommended to forgive your brethren in iman for whatever wrong they may have done to you. On the other hand, you should ask your brethren in iman to forgive you for the intentional and unintentional wrong you may have done to them.
