Page "Islamic–Jewish relations" Paragraph 8

Among the things Muhammad did in order to settle down the longstanding grievances among the tribes of Medina was drafting a document known as the Constitution of Medina.

The community defined in the Constitution of Medina had a religious outlook but was also shaped by the practical considerations and substantially preserved the legal forms of the old Arab tribes.

Muhammad also adopted some features of the Jewish worship and customs such as fasting on the Yom Kippur day.

According to Alford Welch, the Jewish practice of having three daily prayer rituals appears to have been a factor in the introduction of the Islamic midday prayer but that Muhammad's adoption of facing north towards Qiblah ( position of Jerusalem-Islam's first Qiblah or direction of prayer, and now present Qiblah towards Kabah in Makkah ) when performing the daily prayers however was also practiced among other groups in Arabia.
