What are you going to do with the book? The evocation rites are similar to Abramelin. Are you prepared to fast, abstain from meat, spend your entire time in prayer and remain in seclusion for a month-long just to talk to a Jinni? Lol.
Looking for spells? Love magic, wealth, prosperity? Go for Red Magic by Al-Toukhi.
I have a physical copy, it has only recently been released. It is definitely prayer repetition heavy. An interesting resource to have but not sure I will be prioritising it in my practice. If you are keen on it, buy it.
