The root غ م م (gh-m-m) in the Quran

وَظَلَّلْنَا عَلَيْكُمُ ٱلْغَمَامَ وَأَنزَلْنَا عَلَيْكُمُ ٱلْمَنَّ وَٱلسَّلْوَىٰ كُلُوا۟ مِن طَيِّبَٰتِ مَا رَزَقْنَٰكُمْ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ ۝٥٧

And We shaded you with clouds and sent down to you manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not - but they were [only] wronging themselves.

هَلْ يَنظُرُونَ إِلَّآ أَن يَأْتِيَهُمُ ٱللَّهُ فِى ظُلَلٍ مِّنَ ٱلْغَمَامِ وَٱلْمَلَٰٓئِكَةُ وَقُضِىَ ٱلْأَمْرُ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ ۝٢١٠

Do they await but that Allāh should come to them in covers of clouds and the angels [as well] and the matter is [then] decided? And to Allāh [all] matters are returned.

إِذْ تُصْعِدُونَ وَلَا تَلْوُۥنَ عَلَىٰٓ أَحَدٍ وَٱلرَّسُولُ يَدْعُوكُمْ فِىٓ أُخْرَىٰكُمْ فَأَثَٰبَكُمْ غَمًّۢا بِغَمٍّ لِّكَيْلَا تَحْزَنُوا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا مَآ أَصَٰبَكُمْ وَٱللَّهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ ۝١٥٣

[Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allāh repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allāh is [fully] Aware of what you do.

ثُمَّ أَنزَلَ عَلَيْكُم مِّنۢ بَعْدِ ٱلْغَمِّ أَمَنَةً نُّعَاسًا يَغْشَىٰ طَآئِفَةً مِّنكُمْ وَطَآئِفَةٌ قَدْ أَهَمَّتْهُمْ أَنفُسُهُمْ يَظُنُّونَ بِٱللَّهِ غَيْرَ ٱلْحَقِّ ظَنَّ ٱلْجَٰهِلِيَّةِ يَقُولُونَ هَل لَّنَا مِنَ ٱلْأَمْرِ مِن شَىْءٍ قُلْ إِنَّ ٱلْأَمْرَ كُلَّهُۥ لِلَّهِ يُخْفُونَ فِىٓ أَنفُسِهِم مَّا لَا يُبْدُونَ لَكَ يَقُولُونَ لَوْ كَانَ لَنَا مِنَ ٱلْأَمْرِ شَىْءٌ مَّا قُتِلْنَا هَٰهُنَا قُل لَّوْ كُنتُمْ فِى بُيُوتِكُمْ لَبَرَزَ ٱلَّذِينَ كُتِبَ عَلَيْهِمُ ٱلْقَتْلُ إِلَىٰ مَضَاجِعِهِمْ وَلِيَبْتَلِىَ ٱللَّهُ مَا فِى صُدُورِكُمْ وَلِيُمَحِّصَ مَا فِى قُلُوبِكُمْ وَٱللَّهُ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ۝١٥٤

Then after distress, He sent down upon you security [in the form of] drowsiness, overcoming a faction of you, while another faction worried about themselves, thinking of Allāh other than the truth - the thought of ignorance, saying, "Is there anything for us [to have done] in this matter?" Say, "Indeed, the matter belongs completely to Allāh." They conceal within themselves what they will not reveal to you. They say, "If there was anything we could have done in the matter, we [i.e., some of us] would not have been killed right here." Say, "Even if you had been inside your houses, those decreed to be killed would have come out to their death beds." [It was] so that Allāh might test what is in your breasts and purify what is in your hearts. And Allāh is Knowing of that within the breasts.

وَقَطَّعْنَٰهُمُ ٱثْنَتَىْ عَشْرَةَ أَسْبَاطًا أُمَمًا وَأَوْحَيْنَآ إِلَىٰ مُوسَىٰٓ إِذِ ٱسْتَسْقَىٰهُ قَوْمُهُۥٓ أَنِ ٱضْرِب بِّعَصَاكَ ٱلْحَجَرَ فَٱنۢبَجَسَتْ مِنْهُ ٱثْنَتَا عَشْرَةَ عَيْنًا قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ وَظَلَّلْنَا عَلَيْهِمُ ٱلْغَمَٰمَ وَأَنزَلْنَا عَلَيْهِمُ ٱلْمَنَّ وَٱلسَّلْوَىٰ كُلُوا۟ مِن طَيِّبَٰتِ مَا رَزَقْنَٰكُمْ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ ۝١٦٠

And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people [i.e., tribe] knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves.

وَٱتْلُ عَلَيْهِمْ نَبَأَ نُوحٍ إِذْ قَالَ لِقَوْمِهِۦ يَٰقَوْمِ إِن كَانَ كَبُرَ عَلَيْكُم مَّقَامِى وَتَذْكِيرِى بِـَٔايَٰتِ ٱللَّهِ فَعَلَى ٱللَّهِ تَوَكَّلْتُ فَأَجْمِعُوٓا۟ أَمْرَكُمْ وَشُرَكَآءَكُمْ ثُمَّ لَا يَكُنْ أَمْرُكُمْ عَلَيْكُمْ غُمَّةً ثُمَّ ٱقْضُوٓا۟ إِلَىَّ وَلَا تُنظِرُونِ ۝٧١

And recite to them the news of Noah, when he said to his people, "O my people, if my residence and my reminding of the signs of Allāh has become burdensome upon you - then I have relied upon Allāh. So resolve upon your plan and [call upon] your associates. Then let not your plan be obscure to you. Then carry it out upon me and do not give me respite.

إِذْ تَمْشِىٓ أُخْتُكَ فَتَقُولُ هَلْ أَدُلُّكُمْ عَلَىٰ مَن يَكْفُلُهُۥ فَرَجَعْنَٰكَ إِلَىٰٓ أُمِّكَ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ وَقَتَلْتَ نَفْسًا فَنَجَّيْنَٰكَ مِنَ ٱلْغَمِّ وَفَتَنَّٰكَ فُتُونًا فَلَبِثْتَ سِنِينَ فِىٓ أَهْلِ مَدْيَنَ ثُمَّ جِئْتَ عَلَىٰ قَدَرٍ يَٰمُوسَىٰ ۝٤٠

[And We favored you] when your sister went and said, 'Shall I direct you to someone who will be responsible for him?' So We restored you to your mother that she might be content and not grieve. And you killed someone, but We saved you from retaliation and tried you with a [severe] trial. And you remained [some] years among the people of Madyan. Then you came [here] at the decreed time, O Moses.

فَٱسْتَجَبْنَا لَهُۥ وَنَجَّيْنَٰهُ مِنَ ٱلْغَمِّ وَكَذَٰلِكَ نُـۨجِى ٱلْمُؤْمِنِينَ ۝٨٨

So We responded to him and saved him from the distress. And thus do We save the believers.

كُلَّمَآ أَرَادُوٓا۟ أَن يَخْرُجُوا۟ مِنْهَا مِنْ غَمٍّ أُعِيدُوا۟ فِيهَا وَذُوقُوا۟ عَذَابَ ٱلْحَرِيقِ ۝٢٢

Every time they want to get out of it [i.e., Hellfire] from anguish, they will be returned to it, and [it will be said], "Taste the punishment of the Burning Fire!"

وَيَوْمَ تَشَقَّقُ ٱلسَّمَآءُ بِٱلْغَمَٰمِ وَنُزِّلَ ٱلْمَلَٰٓئِكَةُ تَنزِيلًا ۝٢٥

And [mention] the Day when the heaven will split open with [emerging] clouds, and the angels will be sent down in successive descent.
