The root غ ل م (gh-l-m) in the Quran

قَالَ رَبِّ أَنَّىٰ يَكُونُ لِى غُلَٰمٌ وَقَدْ بَلَغَنِىَ ٱلْكِبَرُ وَٱمْرَأَتِى عَاقِرٌ قَالَ كَذَٰلِكَ ٱللَّهُ يَفْعَلُ مَا يَشَآءُ ۝٤٠

He said, "My Lord, how will I have a boy when I have reached old age and my wife is barren?" He [the angel] said, "Such is Allāh; He does what He wills."

وَجَآءَتْ سَيَّارَةٌ فَأَرْسَلُوا۟ وَارِدَهُمْ فَأَدْلَىٰ دَلْوَهُۥ قَالَ يَٰبُشْرَىٰ هَٰذَا غُلَٰمٌ وَأَسَرُّوهُ بِضَٰعَةً وَٱللَّهُ عَلِيمٌۢ بِمَا يَعْمَلُونَ ۝١٩

And there came a company of travelers; then they sent their water drawer, and he let down his bucket. He said, "Good news! Here is a boy." And they concealed him, [taking him] as merchandise; and Allāh was Knowing of what they did.

قَالُوا۟ لَا تَوْجَلْ إِنَّا نُبَشِّرُكَ بِغُلَٰمٍ عَلِيمٍ ۝٥٣

[The angels] said, "Fear not. Indeed, we give you good tidings of a learned boy."

فَٱنطَلَقَا حَتَّىٰٓ إِذَا لَقِيَا غُلَٰمًا فَقَتَلَهُۥ قَالَ أَقَتَلْتَ نَفْسًا زَكِيَّةًۢ بِغَيْرِ نَفْسٍ لَّقَدْ جِئْتَ شَيْـًٔا نُّكْرًا ۝٧٤

So they set out, until when they met a boy, he [i.e., al-Khiḍr] killed him. [Moses] said, "Have you killed a pure soul for other than [having killed] a soul? You have certainly done a deplorable thing."

وَأَمَّا ٱلْغُلَٰمُ فَكَانَ أَبَوَاهُ مُؤْمِنَيْنِ فَخَشِينَآ أَن يُرْهِقَهُمَا طُغْيَٰنًا وَكُفْرًا ۝٨٠

And as for the boy, his parents were believers, and we feared that he would overburden them by transgression and disbelief.

وَأَمَّا ٱلْجِدَارُ فَكَانَ لِغُلَٰمَيْنِ يَتِيمَيْنِ فِى ٱلْمَدِينَةِ وَكَانَ تَحْتَهُۥ كَنزٌ لَّهُمَا وَكَانَ أَبُوهُمَا صَٰلِحًا فَأَرَادَ رَبُّكَ أَن يَبْلُغَآ أَشُدَّهُمَا وَيَسْتَخْرِجَا كَنزَهُمَا رَحْمَةً مِّن رَّبِّكَ وَمَا فَعَلْتُهُۥ عَنْ أَمْرِى ذَٰلِكَ تَأْوِيلُ مَا لَمْ تَسْطِع عَّلَيْهِ صَبْرًا ۝٨٢

And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure for them, and their father had been righteous. So your Lord intended that they reach maturity and extract their treasure, as a mercy from your Lord. And I did it not of my own accord. That is the interpretation of that about which you could not have patience."

يَٰزَكَرِيَّآ إِنَّا نُبَشِّرُكَ بِغُلَٰمٍ ٱسْمُهُۥ يَحْيَىٰ لَمْ نَجْعَل لَّهُۥ مِن قَبْلُ سَمِيًّا ۝٧

[He was told], "O Zechariah, indeed We give you good tidings of a boy whose name will be John. We have not assigned to any before [this] name."

قَالَ رَبِّ أَنَّىٰ يَكُونُ لِى غُلَٰمٌ وَكَانَتِ ٱمْرَأَتِى عَاقِرًا وَقَدْ بَلَغْتُ مِنَ ٱلْكِبَرِ عِتِيًّا ۝٨

He said, "My Lord, how will I have a boy when my wife has been barren and I have reached extreme old age?"

قَالَ إِنَّمَآ أَنَا۠ رَسُولُ رَبِّكِ لِأَهَبَ لَكِ غُلَٰمًا زَكِيًّا ۝١٩

He said, "I am only the messenger of your Lord to give you [news of] a pure boy [i.e., son]."

قَالَتْ أَنَّىٰ يَكُونُ لِى غُلَٰمٌ وَلَمْ يَمْسَسْنِى بَشَرٌ وَلَمْ أَكُ بَغِيًّا ۝٢٠

She said, "How can I have a boy while no man has touched me and I have not been unchaste?"

فَبَشَّرْنَٰهُ بِغُلَٰمٍ حَلِيمٍ ۝١٠١

So We gave him good tidings of a forbearing boy.

فَأَوْجَسَ مِنْهُمْ خِيفَةً قَالُوا۟ لَا تَخَفْ وَبَشَّرُوهُ بِغُلَٰمٍ عَلِيمٍ ۝٢٨

And he felt from them apprehension. They said, "Fear not," and gave him good tidings of a learned boy.

وَيَطُوفُ عَلَيْهِمْ غِلْمَانٌ لَّهُمْ كَأَنَّهُمْ لُؤْلُؤٌ مَّكْنُونٌ ۝٢٤

There will circulate among them [servant] boys [especially] for them, as if they were pearls well-protected.
