Sura al-Tawbah 9:40

إِلَّا تَنصُرُوهُ فَقَدْ نَصَرَهُ ٱللَّـهُ إِذْ أَخْرَجَهُ ٱلَّذِينَ كَفَرُوا۟ ثَانِىَ ٱثْنَيْنِ إِذْ هُمَا فِى ٱلْغَارِ إِذْ يَقُولُ لِصَٰحِبِهِۦ لَا تَحْزَنْ إِنَّ ٱللَّـهَ مَعَنَا فَأَنزَلَ ٱللَّـهُ سَكِينَتَهُۥ عَلَيْهِ وَأَيَّدَهُۥ بِجُنُودٍ لَّمْ تَرَوْهَا وَجَعَلَ كَلِمَةَ ٱلَّذِينَ كَفَرُوا۟ ٱلسُّفْلَىٰ وَكَلِمَةُ ٱللَّـهِ هِىَ ٱلْعُلْيَا وَٱللَّـهُ عَزِيزٌ حَكِيمٌ

illā tanṣurūhu fa-qad naṣarahu allāhu idh akhrajahu lladhīna kafarū thāniya ithnayni idh humā fī l-ghāri idh yaqūlu li-ṣāḥibihi lā taḥzan inna allāha maʿanā fa-anzala allāhu sakīnatahu ʿalayhi wa-ayyadahu bi-junūdin lam tarawhā wa-jaʿala kalimata lladhīna kafarū l-suflā wa-kalimatu allāhi hiya l-ʿulyā wallāhu ʿazīzun ḥakīmun

If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise.

Sura al-Naḥl 16:127

وَٱصْبِرْ وَمَا صَبْرُكَ إِلَّا بِٱللَّـهِ وَلَا تَحْزَنْ عَلَيْهِمْ وَلَا تَكُ فِى ضَيْقٍ مِّمَّا يَمْكُرُونَ

wa-iṣbir wa-mā ṣabruka illā billāhi wa-lā taḥzan ʿalayhim wa-lā taku fī ḍayqin mimmā yamkurūna

And do thou be patient, for thy patience is but from Allah; nor grieve over them: and distress not thyself because of their plots.

Sura Maryam 19:24

فَنَادَىٰهَا مِن تَحْتِهَآ أَلَّا تَحْزَنِى قَدْ جَعَلَ رَبُّكِ تَحْتَكِ سَرِيًّا

fanādahā min taḥtihā allā taḥzanī qad jaʿala rabbuki taḥtaki sariyyan

But (a voice) cried to her from beneath the (palm-tree): "Grieve not! for thy Lord hath provided a rivulet beneath thee;

Sura Ṭā Hā 20:40

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

"Behold! thy sister goeth forth and saith, 'shall I show you one who will nurse and rear the (child)?' So We brought thee back to thy mother, that her eye might be cooled and she should not grieve. Then thou didst slay a man, but We saved thee from trouble, and We tried thee in various ways. Then didst thou tarry a number of years with the people of Midian. Then didst thou come hither as ordained, O Moses!

Sura al-Naml 27:70

وَلَا تَحْزَنْ عَلَيْهِمْ وَلَا تَكُن فِى ضَيْقٍ مِّمَّا يَمْكُرُونَ

wa-lā taḥzan ʿalayhim wa-lā takun fī ḍayqin mimmā yamkurūna

But grieve not over them, nor distress thyself because of their plots.

Sura al-Qaṣaṣ 28:7

وَأَوْحَيْنَآ إِلَىٰٓ أُمِّ مُوسَىٰٓ أَنْ أَرْضِعِيهِ فَإِذَا خِفْتِ عَلَيْهِ فَأَلْقِيهِ فِى ٱلْيَمِّ وَلَا تَخَافِى وَلَا تَحْزَنِىٓ إِنَّا رَآدُّوهُ إِلَيْكِ وَجَاعِلُوهُ مِنَ ٱلْمُرْسَلِينَ

wa-awḥaynā ila ummi mūsā an arḍiʿīhi fa-idhā khifti ʿalayhi fa-alqīhi fī l-yammi wa-lā takhāfī wa-lā taḥzanī innā rāddūhu ilayki wa-jāʿilūhu mina l-mursalīna

So We sent this inspiration to the mother of Moses: "Suckle (thy child), but when thou hast fears about him, cast him into the river, but fear not nor grieve: for We shall restore him to thee, and We shall make him one of Our messengers."

Sura al-Qaṣaṣ 28:13

فَرَدَدْنَٰهُ إِلَىٰٓ أُمِّهِۦ كَىْ تَقَرَّ عَيْنُهَا وَلَا تَحْزَنَ وَلِتَعْلَمَ أَنَّ وَعْدَ ٱللَّـهِ حَقٌّ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ

fa-radadnāhu ila ummihi kay taqarra ʿaynuhā wa-lā taḥzana wa-litaʿlama annā waʿda allāhi ḥaqqun wa-lākinna aktharahum lā yaʿlamūna

Thus did We restore him to his mother, that her eye might be comforted, that she might not grieve, and that she might know that the promise of Allah is true: but most of them do not understand.

Sura al-Aḥzāb 33:51

تُرْجِى مَن تَشَآءُ مِنْهُنَّ وَتُـْٔوِىٓ إِلَيْكَ مَن تَشَآءُ وَمَنِ ٱبْتَغَيْتَ مِمَّنْ عَزَلْتَ فَلَا جُنَاحَ عَلَيْكَ ذَٰلِكَ أَدْنَىٰٓ أَن تَقَرَّ أَعْيُنُهُنَّ وَلَا يَحْزَنَّ وَيَرْضَيْنَ بِمَآ ءَاتَيْتَهُنَّ كُلُّهُنَّ وَٱللَّـهُ يَعْلَمُ مَا فِى قُلُوبِكُمْ وَكَانَ ٱللَّـهُ عَلِيمًا حَلِيمًا

turjī man tashāʾu minhunna wa-tuʾwī ilayka man tashāʾu wa-mani ibtaghayta mimman ʿazalta fa-lā junāḥa ʿalayka dhālika adnā an taqarra aʿyunuhunna wa-lā yaḥzanna wa-yarḍayna bimā ātaytahunna kulluhunna wallāhu yaʿlamu mā fī qulūbikum wa-kāna allāhu ʿalīman ḥalīman

Thou mayest defer (the turn of) any of them that thou pleasest, and thou mayest receive any thou pleasest: and there is no blame on thee if thou invite one whose (turn) thou hadst set aside. This were nigher to the cooling of their eyes, the prevention of their grief, and their satisfaction - that of all of them - with that which thou hast to give them: and Allah knows (all) that is in your hearts: and Allah is All-Knowing, Most Forbearing.
