Is It Obligatory to Believe in the Kalam Cosmological Argument?

Answered by Shaykh Faraz Rabbani


There are some theistic believing Physicists who have spoken up on certain articulations of the Kalam Cosmological argument, which I understand to be mostly taken from Imam Ghazali. It just makes me uncomfortable and would be comforted if I knew that ULTIMATELY only Allah knows what exactly did happen and that argumentation cannot prove God.

Thank you for all you do!


I hope you’re doing well, insha’Allah. May Allah bless you for your concern.

The priority is to learn one’s faith, and its explanation soundly. Knowing the rational proofs in detail, with their nuances, isn’t personally obligatory. Rather, it is a communal obligation (fard kifaya). [Bajuri, Tuhfat al-Murid ‘ala Jawharat al-Tawhid; Sajiqlizada, Nashr al-Tawali‘; Ibn ‘Arafa, al-Mukhtasar al-Kalami]

The nuances of various Kalam arguments–and there are many rational pathways to affirm the existence, entity, and attributes of God discussed in our scholarly tradition, classical and in contemporary scholarship.

Even what is presented as “the” Kalam Cosmological Argument is only one of many such rational proofs–and its variants and nuances, and also its contemporary applications–are discussed and argued by Muslim theologians, classical and contemporary.

Kalam and Islam by Shaykh Nuh Ha Mim Keller

Accepting any one argument isn’t itself a direct religious duty. The direct religious duty is to believe in Allah and the Messenger (peace and blessings be upon him), and to affirm what is decisively established and necessarily known to be of the religion.

And Allah is the giver of success and facilitation.
