Sura al-Baqara 2:255

ٱللَّـهُ لَآ إِلَٰهَ إِلَّا هُوَ ٱلْحَىُّ ٱلْقَيُّومُ لَا تَأْخُذُهُۥ سِنَةٌ وَلَا نَوْمٌ لَّهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ مَن ذَا ٱلَّذِى يَشْفَعُ عِندَهُۥٓ إِلَّا بِإِذْنِهِۦ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَىْءٍ مِّنْ عِلْمِهِۦٓ إِلَّا بِمَا شَآءَ وَسِعَ كُرْسِيُّهُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ وَلَا يَـُٔودُهُۥ حِفْظُهُمَا وَهُوَ ٱلْعَلِىُّ ٱلْعَظِيمُ

allāhu lā ilāha illā huwa l-ḥayyu l-qayyūmu lā takhudhuhu sinatun wa-lā nawmun lahu mā fī l-samāwāti wa-mā fī l-arḍi man dhā alladhī yashfaʿu ʿindahu illā bi-idhnihi yaʿlamu mā bayna aydīhim wa-mā khalfahum wa-lā yuḥīṭūna bi-shayʾin min ʿilmihi illā bi-mā shāʾa wasiʿa kursīyuhu l-samāwāti wa-l-arḍa wa-lā yaʾūduhu ḥifẓuhumā wa-huwa l-ʿaliyyu l-ʿaẓīmu

Allah! There is no god but He,-the Living, the Self-subsisting, Eternal. No slumber can seize Him nor sleep. His are all things in the heavens and on earth. Who is there can intercede in His presence except as He permitteth? He knoweth what (appeareth to His creatures as) before or after or behind them. Nor shall they compass aught of His knowledge except as He willeth. His Throne doth extend over the heavens and the earth, and He feeleth no fatigue in guarding and preserving them for He is the Most High, the Supreme (in glory).

Sura al-Nisāʾ 4:85

مَّن يَشْفَعْ شَفَٰعَةً حَسَنَةً يَكُن لَّهُۥ نَصِيبٌ مِّنْهَا وَمَن يَشْفَعْ شَفَٰعَةً سَيِّئَةً يَكُن لَّهُۥ كِفْلٌ مِّنْهَا وَكَانَ ٱللَّـهُ عَلَىٰ كُلِّ شَىْءٍ مُّقِيتًا

man yashfaʿ shafāʿatan ḥasanatan yakun lahu naṣībun minhā wa-man yashfaʿ shafāʿatan sayyiʾatan yakun lahu kiflun minhā wa-kāna allāhu ʿalā kulli shayʾin muqītan

Whoever recommends and helps a good cause becomes a partner therein: And whoever recommends and helps an evil cause, shares in its burden: And Allah hath power over all things.

Sura al-Aʿrāf 7:53

هَلْ يَنظُرُونَ إِلَّا تَأْوِيلَهُۥ يَوْمَ يَأْتِى تَأْوِيلُهُۥ يَقُولُ ٱلَّذِينَ نَسُوهُ مِن قَبْلُ قَدْ جَآءَتْ رُسُلُ رَبِّنَا بِٱلْحَقِّ فَهَل لَّنَا مِن شُفَعَآءَ فَيَشْفَعُوا۟ لَنَآ أَوْ نُرَدُّ فَنَعْمَلَ غَيْرَ ٱلَّذِى كُنَّا نَعْمَلُ قَدْ خَسِرُوٓا۟ أَنفُسَهُمْ وَضَلَّ عَنْهُم مَّا كَانُوا۟ يَفْتَرُونَ

Do they just wait for the final fulfilment of the event? On the day the event is finally fulfilled, those who disregarded it before will say: "The messengers of our Lord did indeed bring true (tidings). Have we no intercessors now to intercede on our behalf? Or could we be sent back? then should we behave differently from our behaviour in the past." In fact they will have lost their souls, and the things they invented will leave them in the lurch.

Sura al-Anbiyāʾ 21:28

يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يَشْفَعُونَ إِلَّا لِمَنِ ٱرْتَضَىٰ وَهُم مِّنْ خَشْيَتِهِۦ مُشْفِقُونَ

yaʿlamu mā bayna aydīhim wa-mā khalfahum wa-lā yashfaʿūna illā limani irtaḍā wa-hum min khashyatihi mushfiqūna

He knows what is before them, and what is behind them, and they offer no intercession except for those who are acceptable, and they stand in awe and reverence of His (Glory).
