Kissing someone's hand and its ruling is one of the issues that has always been discussed and debated among the followers of religions, especially in the present age and with the expansion of the media, it has become more serious. Since there is no extensive and integrated research conducted on this issue, the question about the ruling of hand kissing is an issue that will need to be explored in order to reach the stage that a good answer is found. From the Imamiyah's point of view, hand kissing is makrooh, except for the honor of a scholar, master, father etc. There are two viewpoints among the Sunnis: According to the first viewpoint, hand kissing is absolutely makrooh, and the owner (of the religion) and many of his follower have taken this view. According to the second viewpoint, all of the Sunni sects (Hanafi, Shafe'ei, Hanbali, and a group of Malekiyah) have elaborated this issue and, in their views, hand kissing for religious purposes (such as knowledge, asceticism, justice, honor, merit, adultness) is permissible or it is mustahab, and therefore it is permissible to kiss the hand of the scholar, the righteous man, the just ruler, and so on. Shafe'ei jurists also state that it is mustahab to kiss the hand of Sadats who are the children of Hazrat Fatima (s)-because of the honor of the family-but it is makrooh to kiss the hand because of worldly issues(such as wealth, status, etc. ). Narratives have always been the main reason for those who believe in the permissibility or non-permissibility of hand kissing which of course, based on some of the arguments, the narratives that indicate the permissibility of the hand kissing-in terms of quantity, quality, and implication-are preferable to the narratives that indicate the sanctity of the hand kissing. In addition to hand kissing, kissing on the cheeks, forehead, eyes, glabella, face, head, etc., is also permissible. This study has been carried out with the aim of recognizing the arguments and explaining the ruling of hand kissing, which based on most of Imamiyah jurists, including Hanafiyah, Shafe'ei, Hanbaliyah and a group of Malekiyah, is considered permissible for religious purposes.
