Sura al-Anʿām 6:158

هَلْ يَنظُرُونَ إِلَّآ أَن تَأْتِيَهُمُ ٱلْمَلَٰٓئِكَةُ أَوْ يَأْتِىَ رَبُّكَ أَوْ يَأْتِىَ بَعْضُ ءَايَٰتِ رَبِّكَ يَوْمَ يَأْتِى بَعْضُ ءَايَٰتِ رَبِّكَ لَا يَنفَعُ نَفْسًا إِيمَٰنُهَا لَمْ تَكُنْ ءَامَنَتْ مِن قَبْلُ أَوْ كَسَبَتْ فِىٓ إِيمَٰنِهَا خَيْرًا قُلِ ٱنتَظِرُوٓا۟ إِنَّا مُنتَظِرُونَ

hal yanẓurūna illā an taʾtiyahumu l-malāʾikatu aw yaʾtiya rabbuka aw yaʾtiya baʿḍu āyāti rabbika yawma yaʾtī baʿḍu āyāti rabbika lā yanfaʿu nafsan īmānuhā lam takun āmanat min qablu aw kasabat fī īmānihā khayran quli antaẓirū innā muntaẓirūna

Are they waiting to see if the angels come to them, or thy Lord (Himself), or certain of the signs of thy Lord! the day that certain of the signs of thy Lord do come, no good will it do to a soul to believe in them then if it believed not before nor earned righteousness through its faith. Say: "Wait ye: we too are waiting."
