Sura al-Baqara 2:143

وَكَذَٰلِكَ جَعَلْنَٰكُمْ أُمَّةً وَسَطًا لِّتَكُونُوا۟ شُهَدَآءَ عَلَى ٱلنَّاسِ وَيَكُونَ ٱلرَّسُولُ عَلَيْكُمْ شَهِيدًا وَمَا جَعَلْنَا ٱلْقِبْلَةَ ٱلَّتِى كُنتَ عَلَيْهَآ إِلَّا لِنَعْلَمَ مَن يَتَّبِعُ ٱلرَّسُولَ مِمَّن يَنقَلِبُ عَلَىٰ عَقِبَيْهِ وَإِن كَانَتْ لَكَبِيرَةً إِلَّا عَلَى ٱلَّذِينَ هَدَى ٱللَّـهُ وَمَا كَانَ ٱللَّـهُ لِيُضِيعَ إِيمَٰنَكُمْ إِنَّ ٱللَّـهَ بِٱلنَّاسِ لَرَءُوفٌ رَّحِيمٌ

wa-ka-dhālika jaʿalnākum ummatan wasaṭan li-takūnū shuhadāʾa ʿalā l-nāsi wa-yakūna l-rasūlu ʿalaykum shahīdan wa-mā jaʿalnā l-qiblata allatī kunta ʿalayhā illā linaʿlama man yattabiʿu l-rasūla mimman yanqalibu ʿalā ʿaqibayhi wa-in kānat la-kabīratan illā ʿalā lladhīna hadā allāhu wa-mā kāna allāhu li-yuḍīʿa īmānakum inna allāha bil-nāsi la-raʾūfun raḥīmun

Thus, have We made of you an Ummat justly balanced, that ye might be witnesses over the nations, and the Messenger a witness over yourselves; and We appointed the Qibla to which thou wast used, only to test those who followed the Messenger from those who would turn on their heels (From the Faith). Indeed it was (A change) momentous, except to those guided by Allah. And never would Allah Make your faith of no effect. For Allah is to all people Most surely full of kindness, Most Merciful.

Sura Āl-ʿImrān 3:144

وَمَا مُحَمَّدٌ إِلَّا رَسُولٌ قَدْ خَلَتْ مِن قَبْلِهِ ٱلرُّسُلُ أَفَإِي۟ن مَّاتَ أَوْ قُتِلَ ٱنقَلَبْتُمْ عَلَىٰٓ أَعْقَٰبِكُمْ وَمَن يَنقَلِبْ عَلَىٰ عَقِبَيْهِ فَلَن يَضُرَّ ٱللَّـهَ شَيْـًٔا وَسَيَجْزِى ٱللَّـهُ ٱلشَّٰكِرِينَ

wa-mā muḥammadun illā rasūlun qad khalat min qablihi l-rusulu a-fa-īn māta aw qutila inqalabtum ʿala aʿqābikum wa-man yanqalib ʿalā ʿaqibayhi fa-lan yaḍurra allāha shayʾan wasayajzī allāhu l-shākirīna

Muhammad is no more than a messenger: many Were the messenger that passed away before him. If he died or were slain, will ye then Turn back on your heels? If any did turn back on his heels, not the least harm will he do to Allah; but Allah (on the other hand) will swiftly reward those who (serve Him) with gratitude.

Sura al-Kahf 18:42

وَأُحِيطَ بِثَمَرِهِۦ فَأَصْبَحَ يُقَلِّبُ كَفَّيْهِ عَلَىٰ مَآ أَنفَقَ فِيهَا وَهِىَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا وَيَقُولُ يَٰلَيْتَنِى لَمْ أُشْرِكْ بِرَبِّىٓ أَحَدًا

wa-uḥīṭa bithamarihi fa-aṣbaḥa yuqallibu kaffayhi ʿalā mā anfaqa fīhā wahiya khāwiyatun ʿalā ʿurūshihā wa-yaqūlu yā-laytanī lam ushrik bi-rabbī aḥadan

So his fruits (and enjoyment) were encompassed (with ruin), and he remained twisting and turning his hands over what he had spent on his property, which had (now) tumbled to pieces to its very foundations, and he could only say, "Woe is me! Would I had never ascribed partners to my Lord and Cherisher!"

Sura al-Ḥajj 22:11

وَمِنَ ٱلنَّاسِ مَن يَعْبُدُ ٱللَّـهَ عَلَىٰ حَرْفٍ فَإِنْ أَصَابَهُۥ خَيْرٌ ٱطْمَأَنَّ بِهِۦ وَإِنْ أَصَابَتْهُ فِتْنَةٌ ٱنقَلَبَ عَلَىٰ وَجْهِهِۦ خَسِرَ ٱلدُّنْيَا وَٱلْأَخِرَةَ ذَٰلِكَ هُوَ ٱلْخُسْرَانُ ٱلْمُبِينُ

wa-mina l-nāsi man yaʿbudu allāha ʿalā ḥarfin fa-in aṣābahu khayrun iṭmaʾanna bihi wa-in aṣābathu fitnatun inqalaba ʿalā wajhihi khasira l-dunyā wa-l-akhirata dhālika huwa l-khusrānu l-mubīnu

There are among men some who serve Allah, as it were, on the verge: if good befalls them, they are, therewith, well content; but if a trial comes to them, they turn on their faces: they lose both this world and the Hereafter: that is loss for all to see!

Sura al-Nūr 24:37

رِجَالٌ لَّا تُلْهِيهِمْ تِجَٰرَةٌ وَلَا بَيْعٌ عَن ذِكْرِ ٱللَّـهِ وَإِقَامِ ٱلصَّلَوٰةِ وَإِيتَآءِ ٱلزَّكَوٰةِ يَخَافُونَ يَوْمًا تَتَقَلَّبُ فِيهِ ٱلْقُلُوبُ وَٱلْأَبْصَٰرُ

rijālun lā tulhīhim tijāratun wa-lā bayʿun ʿan dhikri allāhi wa-iqāmi l-ṣalawti wa-ītāʾi l-zakawti yakhāfūna yawman tataqallabu fīhi l-qulūbu wa-l-abṣāru

By men whom neither traffic nor merchandise can divert from the Remembrance of Allah, nor from regular Prayer, nor from the practice of regular Charity: Their (only) fear is for the Day when hearts and eyes will be transformed (in a world wholly new),-

Sura al-Nūr 24:44

يُقَلِّبُ ٱللَّـهُ ٱلَّيْلَ وَٱلنَّهَارَ إِنَّ فِى ذَٰلِكَ لَعِبْرَةً لِّأُو۟لِى ٱلْأَبْصَٰرِ

yuqallibu allāhu l-layla wa-l-nahāra inna fī dhālika la-ʿibratan li-lūlī l-abṣāri

It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision!

Sura al-Aḥzāb 33:66

يَوْمَ تُقَلَّبُ وُجُوهُهُمْ فِى ٱلنَّارِ يَقُولُونَ يَٰلَيْتَنَآ أَطَعْنَا ٱللَّـهَ وَأَطَعْنَا ٱلرَّسُولَا۠

yawma tuqallabu wujūhuhum fī l-nāri yaqūlūna yā-laytanā aṭaʿnā allāha wa-aṭaʿnā al-rasūlā

The Day that their faces will be turned upside down in the Fire, they will say: "Woe to us! Would that we had obeyed Allah and obeyed the Messenger!"

Sura al-Fatḥ 48:12

بَلْ ظَنَنتُمْ أَن لَّن يَنقَلِبَ ٱلرَّسُولُ وَٱلْمُؤْمِنُونَ إِلَىٰٓ أَهْلِيهِمْ أَبَدًا وَزُيِّنَ ذَٰلِكَ فِى قُلُوبِكُمْ وَظَنَنتُمْ ظَنَّ ٱلسَّوْءِ وَكُنتُمْ قَوْمًۢا بُورًا

bal ẓanantum an lan yanqaliba l-rasūlu wa-l-muʾminūna ila ahlīhim abadan wa-zuyyina dhālika fī qulūbikum wa-ẓanantum ẓanna l-sawʾi wa-kuntum qawman būran

"Nay, ye thought that the Messenger and the Believers would never return to their families; this seemed pleasing in your hearts, and ye conceived an evil thought, for ye are a people lost (in wickedness)."

Sura al-Mulk 67:4

ثُمَّ ٱرْجِعِ ٱلْبَصَرَ كَرَّتَيْنِ يَنقَلِبْ إِلَيْكَ ٱلْبَصَرُ خَاسِئًا وَهُوَ حَسِيرٌ

thumma irjiʿi l-baṣara karratayni yanqalib ilayka l-baṣaru khāsiʾan wa-huwa ḥasīrun

Again turn thy vision a second time: (thy) vision will come back to thee dull and discomfited, in a state worn out.

Sura al-Inshiqāq 84:9

وَيَنقَلِبُ إِلَىٰٓ أَهْلِهِۦ مَسْرُورًا

wa-yanqalibu ila ahlihi masrūran

And he will turn to his people, rejoicing!
