The root س و ر (s-w-r) in the Quran

وَإِن كُنتُمْ فِى رَيْبٍ مِّمَّا نَزَّلْنَا عَلَىٰ عَبْدِنَا فَأْتُوا۟ بِسُورَةٍ مِّن مِّثْلِهِۦ وَٱدْعُوا۟ شُهَدَآءَكُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَٰدِقِينَ ۝٢٣

And if you are in doubt about what We have sent down [i.e., the Qur’ān] upon Our Servant [i.e., Prophet Muḥammad (ﷺ)], then produce a sūrah the like thereof and call upon your witnesses [i.e., supporters] other than Allāh, if you should be truthful.

يَحْذَرُ ٱلْمُنَٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌ مَّا تَحْذَرُونَ ۝٦٤

The hypocrites are apprehensive lest a sūrah be revealed about them, informing them of what is in their hearts. Say, "Mock [as you wish]; indeed, Allāh will expose that which you fear."

وَإِذَآ أُنزِلَتْ سُورَةٌ أَنْ ءَامِنُوا۟ بِٱللَّهِ وَجَٰهِدُوا۟ مَعَ رَسُولِهِ ٱسْتَـْٔذَنَكَ أُو۟لُوا۟ ٱلطَّوْلِ مِنْهُمْ وَقَالُوا۟ ذَرْنَا نَكُن مَّعَ ٱلْقَٰعِدِينَ ۝٨٦

And when a sūrah was revealed [enjoining them] to believe in Allāh and to fight with His Messenger, those of wealth among them asked your permission [to stay back] and said, "Leave us to be with them who sit [at home]."

وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَٰذِهِۦٓ إِيمَٰنًا فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ فَزَادَتْهُمْ إِيمَٰنًا وَهُمْ يَسْتَبْشِرُونَ ۝١٢٤

And whenever a sūrah is revealed, there are among them [i.e., the hypocrites] those who say, "Which of you has this increased in faith?" As for those who believed, it has increased them in faith, while they are rejoicing.

وَإِذَا مَآ أُنزِلَتْ سُورَةٌ نَّظَرَ بَعْضُهُمْ إِلَىٰ بَعْضٍ هَلْ يَرَىٰكُم مِّنْ أَحَدٍ ثُمَّ ٱنصَرَفُوا۟ صَرَفَ ٱللَّهُ قُلُوبَهُم بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ ۝١٢٧

And whenever a sūrah is revealed, they look at each other, [as if saying], "Does anyone see you?" and then they dismiss themselves. Allāh has dismissed their hearts because they are a people who do not understand.

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ قُلْ فَأْتُوا۟ بِسُورَةٍ مِّثْلِهِۦ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَٰدِقِينَ ۝٣٨

Or do they say [about the Prophet (ﷺ)], "He invented it?" Say, "Then bring forth a sūrah like it and call upon [for assistance] whomever you can besides Allāh, if you should be truthful."

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ قُلْ فَأْتُوا۟ بِعَشْرِ سُوَرٍ مِّثْلِهِۦ مُفْتَرَيَٰتٍ وَٱدْعُوا۟ مَنِ ٱسْتَطَعْتُم مِّن دُونِ ٱللَّهِ إِن كُنتُمْ صَٰدِقِينَ ۝١٣

Or do they say, "He invented it"? Say, "Then bring ten sūrahs like it that have been invented and call upon [for assistance] whomever you can besides Allāh, if you should be truthful."

أُو۟لَٰٓئِكَ لَهُمْ جَنَّٰتُ عَدْنٍ تَجْرِى مِن تَحْتِهِمُ ٱلْأَنْهَٰرُ يُحَلَّوْنَ فِيهَا مِنْ أَسَاوِرَ مِن ذَهَبٍ وَيَلْبَسُونَ ثِيَابًا خُضْرًا مِّن سُندُسٍ وَإِسْتَبْرَقٍ مُّتَّكِـِٔينَ فِيهَا عَلَى ٱلْأَرَآئِكِ نِعْمَ ٱلثَّوَابُ وَحَسُنَتْ مُرْتَفَقًا ۝٣١

Those will have gardens of perpetual residence; beneath them rivers will flow. They will be adorned therein with bracelets of gold and will wear green garments of fine silk and brocade, reclining therein on adorned couches. Excellent is the reward, and good is the resting place.

إِنَّ ٱللَّهَ يُدْخِلُ ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ جَنَّٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ يُحَلَّوْنَ فِيهَا مِنْ أَسَاوِرَ مِن ذَهَبٍ وَلُؤْلُؤًا وَلِبَاسُهُمْ فِيهَا حَرِيرٌ ۝٢٣

Indeed, Allāh will admit those who believe and do righteous deeds to gardens beneath which rivers flow. They will be adorned therein with bracelets of gold and pearl, and their garments therein will be silk.

سُورَةٌ أَنزَلْنَٰهَا وَفَرَضْنَٰهَا وَأَنزَلْنَا فِيهَآ ءَايَٰتٍۭ بَيِّنَٰتٍ لَّعَلَّكُمْ تَذَكَّرُونَ ۝١

[This is] a sūrah which We have sent down and made [that within it] obligatory and revealed therein verses of clear evidence that you might remember.

جَنَّٰتُ عَدْنٍ يَدْخُلُونَهَا يُحَلَّوْنَ فِيهَا مِنْ أَسَاوِرَ مِن ذَهَبٍ وَلُؤْلُؤًا وَلِبَاسُهُمْ فِيهَا حَرِيرٌ ۝٣٣

[For them are] gardens of perpetual residence which they will enter. They will be adorned therein with bracelets of gold and pearls, and their garments therein will be silk.

وَهَلْ أَتَىٰكَ نَبَؤُا۟ ٱلْخَصْمِ إِذْ تَسَوَّرُوا۟ ٱلْمِحْرَابَ ۝٢١

And has there come to you the news of the adversaries, when they climbed over the wall of [his] prayer chamber -

فَلَوْلَآ أُلْقِىَ عَلَيْهِ أَسْوِرَةٌ مِّن ذَهَبٍ أَوْ جَآءَ مَعَهُ ٱلْمَلَٰٓئِكَةُ مُقْتَرِنِينَ ۝٥٣

Then why have there not been placed upon him bracelets of gold or come with him the angels in conjunction?"

وَيَقُولُ ٱلَّذِينَ ءَامَنُوا۟ لَوْلَا نُزِّلَتْ سُورَةٌ فَإِذَآ أُنزِلَتْ سُورَةٌ مُّحْكَمَةٌ وَذُكِرَ فِيهَا ٱلْقِتَالُ رَأَيْتَ ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ يَنظُرُونَ إِلَيْكَ نَظَرَ ٱلْمَغْشِىِّ عَلَيْهِ مِنَ ٱلْمَوْتِ فَأَوْلَىٰ لَهُمْ ۝٢٠

Those who believe say, "Why has a sūrah not been sent down?" But when a precise sūrah is revealed and battle is mentioned therein, you see those in whose hearts is disease [i.e., hypocrisy] looking at you with a look of one overcome by death. And more appropriate for them [would have been]

يَوْمَ يَقُولُ ٱلْمُنَٰفِقُونَ وَٱلْمُنَٰفِقَٰتُ لِلَّذِينَ ءَامَنُوا۟ ٱنظُرُونَا نَقْتَبِسْ مِن نُّورِكُمْ قِيلَ ٱرْجِعُوا۟ وَرَآءَكُمْ فَٱلْتَمِسُوا۟ نُورًا فَضُرِبَ بَيْنَهُم بِسُورٍ لَّهُۥ بَابٌۢ بَاطِنُهُۥ فِيهِ ٱلرَّحْمَةُ وَظَٰهِرُهُۥ مِن قِبَلِهِ ٱلْعَذَابُ ۝١٣

On the [same] Day the hypocrite men and hypocrite women will say to those who believed, "Wait for us that we may acquire some of your light." It will be said, "Go back behind you and seek light." And a wall will be placed between them with a door, its interior containing mercy, but on the outside of it is torment.

عَٰلِيَهُمْ ثِيَابُ سُندُسٍ خُضْرٌ وَإِسْتَبْرَقٌ وَحُلُّوٓا۟ أَسَاوِرَ مِن فِضَّةٍ وَسَقَىٰهُمْ رَبُّهُمْ شَرَابًا طَهُورًا ۝٢١

Upon them [i.e., the inhabitants] will be green garments of fine silk and brocade. And they will be adorned with bracelets of silver, and their Lord will give them a purifying drink.
