A Primer of Religious Knowledge is an English translation of the Urdu book Diniyat ka Pehlä Risälah. It was one of the earliest instructional books written primarily for children and new converts in the Ahmadiyya Muslim Community. Hazrat Maulana Hakeem Noor-ud-Deen^(ra) wrote this book during the life time of the Promised Messiah^(as), and it was first published in May 1906. This was a time when formalized education was scarce and inaccessible for the general masses.

The book lays out the fundamentals of Islamic worship, etiquette, and ideals.
