The word مرد in the Quran

وَمِمَّنْ حَوْلَكُم مِّنَ ٱلْأَعْرَابِ مُنَٰفِقُونَ وَمِنْ أَهْلِ ٱلْمَدِينَةِ مَرَدُوا۟ عَلَى ٱلنِّفَاقِ لَا تَعْلَمُهُمْ نَحْنُ نَعْلَمُهُمْ سَنُعَذِّبُهُم مَّرَّتَيْنِ ثُمَّ يُرَدُّونَ إِلَىٰ عَذَابٍ عَظِيمٍ ۝١٠١

And among those around you of the bedouins are hypocrites, and [also] from the people of Madīnah. They have persisted in hypocrisy. You, [O Muḥammad], do not know them, [but] We know them. We will punish them twice [in this world]; then they will be returned to a great punishment.

لَهُۥ مُعَقِّبَٰتٌ مِّنۢ بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِۦ يَحْفَظُونَهُۥ مِنْ أَمْرِ ٱللَّهِ إِنَّ ٱللَّهَ لَا يُغَيِّرُ مَا بِقَوْمٍ حَتَّىٰ يُغَيِّرُوا۟ مَا بِأَنفُسِهِمْ وَإِذَآ أَرَادَ ٱللَّهُ بِقَوْمٍ سُوٓءًا فَلَا مَرَدَّ لَهُۥ وَمَا لَهُم مِّن دُونِهِۦ مِن وَالٍ ۝١١

For him [i.e., each one] are successive [angels] before and behind him who protect him by the decree of Allāh. Indeed, Allāh will not change the condition of a people until they change what is in themselves. And when Allāh intends for a people ill, there is no repelling it. And there is not for them besides Him any patron.

وَيَزِيدُ ٱللَّهُ ٱلَّذِينَ ٱهْتَدَوْا۟ هُدًى وَٱلْبَٰقِيَٰتُ ٱلصَّٰلِحَٰتُ خَيْرٌ عِندَ رَبِّكَ ثَوَابًا وَخَيْرٌ مَّرَدًّا ۝٧٦

And Allāh increases those who were guided, in guidance, and the enduring good deeds are better to your Lord for reward and better for recourse.

فَأَقِمْ وَجْهَكَ لِلدِّينِ ٱلْقَيِّمِ مِن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ يَوْمَئِذٍ يَصَّدَّعُونَ ۝٤٣

So direct your face [i.e., self] toward the correct religion before a Day comes from Allāh of which there is no repelling. That Day, they will be divided.

لَا جَرَمَ أَنَّمَا تَدْعُونَنِىٓ إِلَيْهِ لَيْسَ لَهُۥ دَعْوَةٌ فِى ٱلدُّنْيَا وَلَا فِى ٱلْـَٔاخِرَةِ وَأَنَّ مَرَدَّنَآ إِلَى ٱللَّهِ وَأَنَّ ٱلْمُسْرِفِينَ هُمْ أَصْحَٰبُ ٱلنَّارِ ۝٤٣

Assuredly, that to which you invite me has no [response to a] supplication in this world or in the Hereafter; and indeed, our return is to Allāh, and indeed, the transgressors will be companions of the Fire.

وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِن وَلِىٍّ مِّنۢ بَعْدِهِۦ وَتَرَى ٱلظَّٰلِمِينَ لَمَّا رَأَوُا۟ ٱلْعَذَابَ يَقُولُونَ هَلْ إِلَىٰ مَرَدٍّ مِّن سَبِيلٍ ۝٤٤

And he whom Allāh sends astray - for him there is no protector beyond Him. And you will see the wrongdoers, when they see the punishment, saying, "Is there for return [to the former world] any way?"

ٱسْتَجِيبُوا۟ لِرَبِّكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ مَا لَكُم مِّن مَّلْجَإٍ يَوْمَئِذٍ وَمَا لَكُم مِّن نَّكِيرٍ ۝٤٧

Respond to your Lord before a Day comes from Allāh of which there is no repelling. No refuge will you have that Day, nor for you will there be any denial.
