Exegesis of the saying of Allah the Exalted: {Say: If the Most Merciful has a son, then I am the first of those who worship}

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the interpretation of the saying of Allah the Exalted:

Answer:
The first of those who worship Allah the Exalted and Majestic, the first of those who worship Allah, and he did not believe that He has a son. Yes. It is also said regarding "Qul in kana" that "in" here means "ma" (the negating particle). It is not a conditional "in"; rather, it is a negating "in" that comes with the meaning of the negating "ma." "In" comes with the meaning of "ma" in "Inna yattabi'una illa al-zann" (They follow nothing but conjecture), which means "They follow nothing." So, "Qul in kana li al-Rahman walad" (Say: If the Most Merciful had a son) means "Say: [There is] no son for Allah the Exalted and Majestic."
