إِنَّ الْأَبْرَارَ لَفِي نَعِيمٍ وَإِنَّ الْفُجَّارَ لَفِي جَحِيمٍ
The righteous will surely be in bliss, and the wicked will surely be in the Fire. (82:13–14)
Wāw coordinates two independent but contrasting reports. Their shared emphatic and grammatical form supplies a clear connection. By contrast, in “ʿalimat nafsun mā qaddamat wa-akhkharat,” the verbs “qaddamat” and “akhkharat” are coordinated within a construction; this is not exactly the same clause-level faṣl/waṣl problem.
In “innahu ẓanna an lan yaḥūr; balā inna rabbahu kāna bihi baṣīran,” the second statement rejects the earlier negative belief. The appropriate analysis therefore considers the relationship of rebuttal, not the mere presence or absence of wāw.
