1608 - As for what follows, O you people present or perhaps more generally, I am only a human being who is soon to be visited by the Messenger of my Lord, meaning the Angel of Death, and I will respond, that is, die. He alluded to this with the term "respond," implying that it is appropriate to receive him with acceptance, as if he is responding to it by his own choice.
And I am leaving among you two weighty matters, which are termed as such due to their great importance and honor. The first of them is the Book of Allah, which He has placed before you due to its right to be given precedence, offering guidance from misguidance and light from darkness. Whoever holds fast to it and acts upon it will be on guidance, and whoever disregards it will go astray, that is, miss the path of happiness and perish in the arenas of confusion and misery. So hold fast to the Book of Allah and cling to it, for it is the means that leads to the highest ranks and eternal happiness. The second are the People of My House. They are those from whom charity is forbidden, being among His close relatives.
