Make wills concerning Allah’s book

This hadith is about the importance of making a will concerning Allah’s book. A will is an important document that states what should happen to your possessions after you die. In this hadith, Talha asked Abdullah bin Abu 'Aufa if the Prophet Muhammad ﷺ made a will and he replied that he did not make one for himself but instead made one concerning Allah’s book. This means that the Prophet wanted to ensure that his teachings were preserved and followed even after his death. He wanted to ensure that people would continue to learn from his teachings and live according to them in order to be successful in life both here on earth and in the hereafter.
