All religious practices of Islam, namely Salat, Zakat, fasting, and Hajj, came from Abraham generation after generation, while Muhammad contributed the Quran.1, 2, 3
Arabian society before Muhammad, including his idolatrous opponents, observed the five daily Salat prayers as we do, except for using the Ibrahimy Faatihha instead of the Quranic one.1
Fasting was practiced before Muhammad through Abraham, when intercourse was forbidden all Ramadan day and night, and the Quran then permitted it during the nights.1, 2
Prophets before Abraham were given no religious practices, as only belief in God alone was required for salvation in that primitive society.1
The four sacred months were observed before Muhammad, further proving that Islam's religious practices were not initiated by him.1
