«وَيَوْمَ تَقُومُ السَّاعَةُ يُقْسِمُ الْمُجْرِمُونَ مَا لَبِثُوا غَيْرَ سَاعَةٍ»
On the day the Hour rises, the guilty will swear that they remained for no more than an hour.
Al-sāʿah first refers to the appointed Hour of Resurrection, whereas sāʿah later refers to a short span of time. The forms are related, while their contextual meanings differ.
This gives a ground for discussing wordplay resembling jinās. But differences in the definite article and form should not be ignored in an unqualified claim that it is perfect jinās.
