Futuwwa
Futuwwa (Arabic: فتوة, "young-manliness" or "chivalry") is a Sufi term that has some similarities to chivalry and virtue. It was also a name of ethical urban organizations or "guilds" in medieval Muslim realms that emphasised honesty, peacefulness, gentleness, generosity, avoidance of complaint and hospitality in life. According to Ibn Battuta, a member was called fata (youth, pl. fityan) and group leaders were called akhi.
In modern-day Egypt, the term is used for youths who try to do quasi-chivalrous acts such as helping others resist intimidation by rival group.
