Sura al-Anʿām 6:12

قُل لِّمَن مَّا فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ قُل لِلَّـهِ كَتَبَ عَلَىٰ نَفْسِهِ ٱلرَّحْمَةَ لَيَجْمَعَنَّكُمْ إِلَىٰ يَوْمِ ٱلْقِيَٰمَةِ لَا رَيْبَ فِيهِ ٱلَّذِينَ خَسِرُوٓا۟ أَنفُسَهُمْ فَهُمْ لَا يُؤْمِنُونَ

qul lliman mā fī l-samāwāti wa-l-arḍi qul lillāhi kataba ʿalā nafsihi l-raḥmata la-yajmaʿannakum ilā yawmi l-qiyāmati lā rayba fīhi lladhīna khasirū anfusahum fa-hum lā yuʾminūna

Say: "To whom belongeth all that is in the heavens and on earth?" Say: "To Allah. He hath inscribed for Himself (the rule of) Mercy. That He will gather you together for the Day of Judgment, there is no doubt whatever. It is they who have lost their own souls, that will not believe.

Sura al-Anʿām 6:35

وَإِن كَانَ كَبُرَ عَلَيْكَ إِعْرَاضُهُمْ فَإِنِ ٱسْتَطَعْتَ أَن تَبْتَغِىَ نَفَقًا فِى ٱلْأَرْضِ أَوْ سُلَّمًا فِى ٱلسَّمَآءِ فَتَأْتِيَهُم بِـَٔايَةٍ وَلَوْ شَآءَ ٱللَّـهُ لَجَمَعَهُمْ عَلَى ٱلْهُدَىٰ فَلَا تَكُونَنَّ مِنَ ٱلْجَٰهِلِينَ

wa-in kāna kabura ʿalayka iʿrāḍuhum fa-ini istaṭaʿta an tabtaghiya nafaqan fī l-arḍi aw sullaman fī l-samāʾi fa-taʾtiyahum bi-āyatin wa-law shāʾa allāhu lajamaʿahum ʿalā l-hudā fa-lā takūnanna mina l-jāhilīna

If their spurning is hard on thy mind, yet if thou wert able to seek a tunnel in the ground or a ladder to the skies and bring them a sign,- (what good?). If it were Allah's will, He could gather them together unto true guidance: so be not thou amongst those who are swayed by ignorance (and impatience)!
