  • Mohamed left Mecca and traveled to Medina in the year A.D. 622. This event is called the Hegira migration. The Hegira marked the starting point of the Muslim calendar and years are counted from this event.[3]

  • While some blame Islam for the oppression of women, others see it as a means to reform. The status of women in Muslim countries differs as much as the countries themselves. Restrictions often originate not from Islam, but rather from cultural customs sometimes wrongly justified under Islam.[4]

He will turn to the four compass directions (north, south, east, and west) and at each turn will declare the Shahada, or Islamic creed: “God is most great. There is no God but Allah. Muhammad is the prophet of God.”[4]
    • Islam Prayer Fact
    The call of the muezzin is considered an art form
  • In some Islamic traditions, dog saliva is considered ritually impure, and Muslims may wash before prayer if they come into contact with it. While some avoid keeping dogs inside the home for this reason, views vary widely, and dogs are permitted for purposes such as guarding, hunting, and companionship.[2]
  • Both alcohol and pork are forbidden in Islam.[2]
  • Mainstream Islamic teachings prohibit violence against innocent people, and most Muslim scholars strongly condemn acts of terrorism. However, interpretations of religious texts have varied across history, and extremist groups have at times claimed religious justification for violence.[2]
  • Marriage between first cousins is permitted in Islam, as it is in Judaism, and occurs in some regions and cultures. However, its prevalence varies widely and is influenced more by local customs than by religious requirements.[2]
  • Traditional Islamic teachings generally prohibit same-sex sexual activity. In some countries, laws influenced by these interpretations criminalize such relationships, while in others attitudes are more varied. Today, some Muslims advocate for greater inclusion and recognition of LGBTQ individuals within their communities.[2]
  • Islamic scholars differ on the permissibility of abortion, but many consider the stage of “ensoulment” (often placed at around 120 days of pregnancy) to be a key threshold. Abortion is generally more restricted after this point, though most scholars allow it when the mother’s life is at risk. Views vary across different schools of thought and legal traditions.[3]
  • The Quran does not specifically address birth control, though a few hadith mention coitus interruptus. Today, most Muslim scholars agree that temporary contraception is permissible, provided both husband and wife consent. Views may vary regarding permanent methods or abortion.[3]
  • Many Islamic scholars and councils permit organ donation, provided it does not harm a living donor, is done with respect for the deceased, and has proper consent. Saving lives through organ donation is generally considered a charitable and virtuous act in Islam.[3]

    The mosque was founded in 1926 as a token of gratitude for the Muslims who died fighting for France during WW I
  • During World War II, the Grand Mosque of Paris helped some Jews evade Nazi persecution by providing Muslim identity papers and shelter, as part of broader efforts by members of the mosque to protect vulnerable people.[5]
  • Jerusalem is a revered city by all three of the great monotheistic faiths. For Muslims, Jerusalem was the original qibla (location that all Muslims face when they pray) and Mohammad’s destination in his Night Journey from Mecca.[3]
  • Some observers have asked why democratic systems are less widespread in certain Muslim-majority countries. Scholars generally attribute this to historical, political, and social factors rather than Islamic religious teachings.[4]
