«قَدْ تَنَاهَيْنَا فِي الْمُهْلَةِ وَتَمَادَيْنَا فِي الرِّحْلَةِ ... وَبَانَ أَنَّ الرَّجُلَ قَدْ مَانَ»
We had reached the limit of waiting and delayed our journey; it became plain that the man had lied.
Māna means to lie. The narrator moves from suspicion to a conclusion based on the long failure to return.
Tanāhaynā / tamādaynā echo in sound, while both convey the extension of time. The conclusion is narratively earned: permission, hurried departure, festival-like expectation, and the fading day have preceded it.
