Ahmadiyyat or the True Islam was first published in 1924 and has been published many times since. It is an extended treatise of a lecture read at The Conference of Living Religions Within the Empire in London.

The treatise exhaustively deals with the subjects as the conception of God, His relation to man and attainment of Communion with Him. It also deals with the Islamic teachings on morals and their social aspects—relations within family, the community, between partners in business and between government and people. Nature of the human soul, life after death and the nature of heaven and hell have also been addressed. Most important of all is that all the issues dealt with in the treatise have been supported and documented from the Holy Quran and Hadith which places this unique dissertation among the most authentic works on Islam. It is as relevant today as it was when first published to present the true teachings of Islam and to counter hostile propaganda against it.
