Muslims often claim that Allah is the same as Yahweh and that both can swear by their own names.

According to the Scriptures, Yahweh, the God of the Bible, uniquely swears by Himself, which signifies His supreme authority and the absence of any greater being to whom He can appeal. This is evident in verses such as Genesis 22:16 and Hebrews 6:13, where God makes oaths in His own name, underscoring His sovereignty. In contrast, the Quran does not present Allah in the same light, as it lacks the same emphasis on swearing by His own name alone. This difference raises questions about the nature of Allah compared to Yahweh. Furthermore, the Bible instructs believers to take oaths in the name of Yahweh, reinforcing the idea that oaths are sacred and should not invoke other deities. For example, in Numbers 30:1-2, the Israelites are commanded to fulfill their vows to the Lord, indicating that oaths are to be made exclusively in His name. This practice is consistent throughout the Scriptures, as seen in various instances where individuals swear by the name of Yahweh. Moreover, the Scriptures warn against swearing by other gods, as seen in Joshua 23:7, which cautions against mixing with other nations and invoking their names. This highlights the exclusivity of Yahweh in the context of oaths and reinforces the biblical teaching that believers should not invoke any other deity when making promises. The prophetic vision in Isaiah 45:23 further emphasizes that a time will come when all will swear by the name of Yahweh alone, indicating a future fulfillment of this principle. In conclusion, while Muslims may assert that Allah is equivalent to Yahweh and that both can swear by their names, the biblical evidence suggests a clear distinction in the nature and practice of oath-taking between the two. Yahweh's unique position as the supreme being who swears by Himself sets Him apart from Allah, who does not share this characteristic in the same way.
