How is Ayah 3 of Suratul-Ikhlas in the Qur’an, لم يلد ولم يولد [Lam yalid walam yulad] explained?

Listen  

This Ayah means, “Allah does not have offspring, and He is not an offspring of another.” This Ayah states that Allah is clear of being an origin for others or derived from others. Allah does not dwell in things, nor do things dwell in Him.  Imam Ja^far As-Sadiq stated as related by Abul-Qasim Al-Qushayriyy in his book Ar-Risalah Al-Qushayriyyah, “Whoever claims that Allah is in something, on something or from something commits shirk  (a type of blasphemy)”.
