If someone happens to overeating and anticipates indigestion and vomiting, he can keep himself safe from indigestion and vomiting by licking the salt which has been blown after reciting (وَ بِالْحَقِّ اَنْزَلْنٰہُ وَ بِالْحَقِّ نَزَلَ وَمَآ اَرْسَلْنٰکَ اِلَّا مُبَشِّرًا وَّ نَذِیْرًا ﴿۱۰۵for seven times. Besides this ayah cures every disorder. (P, Q)
