Muhammad did not know the meaning of YHWH, as he never used the name in the Quran.

The article begins by addressing the assertion that Muhammad lacked knowledge of the name YHWH. It cites the Jewish Encyclopedia, which defines YHWH as 'He who is self-existing, self-sufficient' and 'The Living and Self-Subsisting.' The author then points out that the Quran refers to Allah with similar attributes, such as al-hayy (the Ever-Living) and al-qayyum (the Self-Subsisting). This suggests that Muhammad was aware of the essence of YHWH, even if he did not use the name directly. Next, the article emphasizes that these qualities are not just coincidental but are foundational to the understanding of Allah in Islam. The author references several Quranic verses that highlight these attributes, demonstrating that the characteristics of YHWH are indeed present in Islamic theology. This serves to bridge the perceived gap between the two faiths regarding the understanding of God's nature. Finally, the article transitions to the New Testament, where Jesus explicitly claims to embody these divine attributes. For instance, in Revelation 1:17-18, Jesus identifies himself as 'the Living One' who lives forever, thus aligning himself with the description of YHWH. This connection is crucial as it reinforces the Christian belief that Jesus is not only aware of but also fulfills the identity of YHWH, countering the claim that Muhammad lacked knowledge of this divine name.
