﴿ فَعَقَرُوهَا فَقَالَ تَمَتَّعُوا۟ فِى دَارِكُمْ ثَلَٰثَةَ أَيَّامٍۢ ۖ ذَٰلِكَ وَعْدٌ غَيْرُ مَكْذُوبٍۢ ﴾

“But they cruelly slaughtered her. And thereupon [Salih] said: "[Only] for three days [more] shall you enjoy life in your homes: this is a judgment which will not be belied!"”

In verse 65, it was said: تَمَتَّعُوا فِي دَارِ‌كُمْ ثَلَاثَةَ أَيَّامٍ "Enjoy yourselves in your homes for three days [ only ]." That is, when these people killed the she-camel associated with the miracle in flagrant contravention of the Di-vine command, then, something serious happened. As warned earlier, ` lest a near punishment should seize you - 64', the punishment did come upon them in a manner that they were given a respite of three days and told that they all will be destroyed on the fourth day.
