Is it permissible for a woman to shake hands with and kiss on the cheeks her father's paternal and maternal uncles? And can the woman's mahrams and non-mahrams be detailed?

A father's paternal uncle or maternal uncle are considered among a woman's mahram (unmarriageable kin), and she is permitted to shake their hands and kiss their cheeks if there is no fear of temptation (fitnah).

The mahram men are: - By lineage: Father, son, brother, paternal uncle, son of brother, son of sister, and maternal uncle. - By breastfeeding: Those who are in the position of mahram by lineage. - By marriage: Husband's father, husband's son, mother's husband (provided consummation occurred with the mother), and daughter's husband.
