and teachers. This was especially the case for learned and scholarly families, who wanted to ensure the highest possible education for both their sons and daughters. Ibn Asakir had himself studied under 80 different female teachers in his time. Female education in the Islamic world was inspired by Muhammad's wives: Khadijah, a successful businesswoman, and Aisha, a renowned hadith scholar and military leader. According to a hadith attributed to Muhammad, he praised the women of Medina because of their desire for religious knowledge: While it was not common for women to enroll as students in formal classes, it was common for women to attend informal lectures and study sessions at mosques, madrasahs and other public places. While there were no legal restrictions on female education, some men did not approve of this practice, such as Muhammad ibn al-Hajj (d. 1336) who was appalled at the behaviour of some women who informally audited lectures in his time: Employment Women under Islamic law could enter into contracts, buy and sell property, sue in court on their own behalf without the need for a man to represent them, engage in commerce, endow trusts, etc., the same as a man. The labor force in the Caliphate were employed from diverse ethnic and religious backgrounds, while both men and women were involved in diverse occupations and economic activities. Women were employed in a wide range of commercial activities and diverse occupations in the primary sector (as farmers for example), secondary sector (as construction workers, dyers, spinners, etc.) and tertiary sector (as investors, doctors, nurses, presidents of guilds, brokers, peddlers, lenders, scholars, etc.). Muslim women also held a monopoly over certain branches of the textile industry, the largest and most specialized and market-oriented industry at the time, in occupations such as spinning, dyeing, and embroidery. In comparison, female property rights and wage labour were relatively uncommon in Europe until the Industrial Revolution in the 18th and 19th centuries. Criminal law Female and male transgressors were treated mostly the same except some instance for example, diya or financial compensation for a crime against a female victim is half that of a male victim. A charge of adultery against a woman requires four eyewitnesses which made it difficult to prosecute. Rape, on the other hand, is a criminal assault offense which does not require four eyewitnesses as if it were a charge of adultery. However, several Muslim-majority countries
