On his head was a bonnet, and he wore something like it while awake

And whoever sees a cap on his head and what he wears like it in wakefulness, if it is white, then it indicates the goodness of his religion, and if it is green, then it indicates the goodness of obedience, worship and good deeds, and if it is red, it indicates a decrease in religion and worship, and if it is yellow, it indicates sickness and hardship. And if it is black, then it is disliked unless he has a habit of wearing it .
