Despite the long difference between the revelation of Judaism and Islam, there are several similarities between them that distinguish them from Christianity and the rest of the non-monotheistic religions.
The first similarity is the belief in one God who has no partner. For Jews, he is Jehovah, or Adonai, the Lord of the universe, and for Muslims, he is the “Samad”, who has no equal to him.
Both religions also rely on the importance of prayer in worship, several times a day. While Muslims pray 5 times a day, Jews are required to pray three times: morning, noon and evening. This is in addition to fasting, which humanity knew before the revelation of religions mainly. Indeed, Muslims fast during the entire month of Ramadan, from dawn to sunset, during which they abstain from food, drink and sexual intercourse, while Jews practice several types of fasting, which can last up to 24 hours and six days, depending on what they celebrate, whether it is Kippur, the Temple memorial or other sacred religious occasions.
Circumcision is also present and mandatory in Judaism and Islam. It is an important religious commandment for the Jews, it was mentioned in the “Book of Genesis”, while a person’s Islam will not be complete if he is not circumcised, even though it is a prophetic Sunna and is not mentioned in the Quran.
Similarities between the two religions include halal food, although Jews do not eat Muslim food, while the reverse is possible, in addition to the method of slaughter (slitting the animal’s throat in one attempt instead of electrocuting it) and the veiling of women.
