﴿وَاتَّقُوا الَّذِي أَمَدَّكُم بِمَا تَعْلَمُونَ﴾
And be mindful of the One who provided you with what you know. (al-Shuʿarāʾ 26:132)
﴿أَمَدَّكُم بِأَنْعَامٍ وَبَنِينَ﴾
He provided you with livestock and sons. (al-Shuʿarāʾ 26:133)
The first statement mentions blessings generally; the second identifies significant instances. The latter clarifies a salient part of the former, producing a relation analogous to substitution at clause level. Omission of a coordinating wāw preserves their close unity instead of presenting them as two independent reports.
