Ehram (إحرام iḥrām, from the root of H-R-M) is, in Islam, a sacred state which a Muslim must enter in order to perform the major pilgrimage (Hajj) or the minor pilgrimage (Umrah). A pilgrim must enter into this state before crossing the pilgramage boundary, known as Miqat, by performing the cleansing rituals and wearing the prescribed attire.
Aside from being as clean as they are for prayer, males are expected to cut their nails, trim their hair and beards, and wear Ihram clothing. Many also shave their head as this is hygienic. Females are expected to dress in proper clothing and to also be clean. At the beginning of a pilgrimage, the Muslim stops at a designated station to perform certain ritual cleansing ceremonies; each male shaves his head, cuts his nails, and trims his beard before donning a white, seamless, two-piece garment. Women also wear white; although no particular dress is prescribed, by tradition they wear long robes. During the period of sanctification, sexual activity, shaving, and cutting one's nails all are forbidden in accordance with the pilgrim's special relationship to God during the ihram.
The word is also used for the state of a worshipper during the performance of the salat, the ritual prayer repeated five times daily.
Certain behavior is also expected. A haajj (someone who performs the Hajj) should refrain from: killing animals or eating meat (thereby causing animals to be killed for them), using profane language, quarelling or fighting, taking an oath, engaging in sexual activity, in addition to any other regularly prohibited acts. Males should also refrain from looking at women and women should exercise strict modesty in their appearance and not to apply make-up or any other cosmetics
