quran:79:10 –

They are ˹presently˺ saying, "Will we indeed be returned to ˹our˺ former state ˹of life˺?  

They, those of the ˹mentioned˺ hearts and eyes, will say, mockingly and in rejection of the Resurrection: ‘Are we indeed (read a-innā pronouncing both hamzas, or by not pronouncing the second, and inserting an alif between them in both cases, and in both instances) being restored as before? Shall we be restored to life after death (al-hāfira is a noun signifying the ‘first part’ of anything, from which is derived the expression raja‘a fī hāfiratihi to mean that so and so ‘returned whence he had come’).
القرآن:٧٩:١٠ –

يَقُولُونَ أَإِنَّا لَمَرْدُودُونَ فِي الْحَافِرَةِ  

{يقولون} أي أرباب القلوب والأبصار استهزاء وإنكارا للبعث {أئنا} بتحقيق الهمزتين وتسهيل الثانية وإدخال الف بينهما على الوجهين في الموضعين {لمردودون في الحافرة} أي أنرد بعد الموت إلى الحياة، والحافرة: اسم لأول الأمر، ومنه رجع فلان في حافرته: إذا رجع من حيث جاء.
