أَنَّهُ يَمْتَنِعُ قِيَامُ الْحَوَادِثِ بِذَاتِهِ تَعَالَى
Originated events cannot subsist in the divine essence.
Once takwīn is understood as a real attribute subsisting in God, to call it originated would mean that the divine essence first lacked it and then acquired a new attribute. The theologians reject this as divine change and the essence becoming a locus of temporal accidents.
Thus the originated product and the attribute subsisting in its Creator must be distinguished: the created thing has a temporal beginning, while the attribute of takwīn is affirmed to be eternal.
