Advice to one of his sons after returning from the Battle of Siffin

w on the stage of the world, possessing upright intention and clean heart and that I should begin with the teaching of the Book of Allah, and its interpretation, the laws of Islam and its commands, its lawful matters and unlawful matters and that I should not go beyond these for you. Then I feared lest you should get confused as other people had been confused on account of their passions and (different) views. Therefore, in spite of my dislike for you being so warned, I thought it better for me to make this position strong rather than leave you in a position where I do not regard you safe from falling into destruction. I hoped that Allah would help you in your straightforwardness and guide you in your resoluteness. Consequently, I wrote this piece of my will for you.

It is better to avoid this. Appreciate my advice, O my child, and know He Who is the Master of death is also the Master of life, that the Creator causes death as well; that He Who destroys is also the restorer of life and that He Who inflicts disease is also the curer. This world continues in the way Allah has made it with regard to its pleasures, trials, rewards on the Day of Judgement and all that He wishes and you do not know. If anything of this advice is not understood by you then attribute it to your ignorance of it, because when you were first born you were born ignorant. Thereafter, you acquired knowledge.
