Whoever sees in a dream that he gives the closing salutation and has come out of his prayer having completed it, he will come out of every worry, and his affair will return to affection. If he gives the salutation to his right, it is the setting right of some of his affairs; and if he gives it to his left and not his right, some of his affairs will become disturbed for him. The salutation after finishing a prayer signifies following in the footsteps [of the righteous] and adhering to the Sunnah, finishing a piece of work, dismissal from office and appointment to office, travel and provision. If he gives the salutation to the left before the right, it signifies following evil and adhering to innovations. If he rises from his prayer without giving the salutation, it is a sign of concern for obtaining profit while neglecting the capital.
