Sura Hūd 11:93

وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌ

wa-yā-qawmi iʿmalū ʿalā makānatikum innī ʿāmilun sawfa taʿlamūna man yaʾtīhi ʿadhābun yukhzīhi wa-man huwa kādhibun wa-irtaqibū innī maʿakum raqībun

"And O my people! Do whatever ye can: I will do (my part): Soon will ye know who it is on whom descends the penalty of ignominy; and who is a liar! and watch ye! for I too am watching with you!"

Sura Ṭā Hā 20:94

قَالَ يَبْنَؤُمَّ لَا تَأْخُذْ بِلِحْيَتِى وَلَا بِرَأْسِىٓ إِنِّى خَشِيتُ أَن تَقُولَ فَرَّقْتَ بَيْنَ بَنِىٓ إِسْرَٰٓءِيلَ وَلَمْ تَرْقُبْ قَوْلِى

qalā ya-bnaʾumma lā taʾkhudh bi-liḥyatī wa-lā bi-raʾsī innī khashītu an taqūla farraqta bayna banī isrāʾīla wa-lam tarqub qawlī

(Aaron) replied: "O son of my mother! Seize (me) not by my beard nor by (the hair of) my head! Truly I feared lest thou shouldst say, 'Thou has caused a division among the children of Israel, and thou didst not respect my word!'"

Sura al-Dukhān 44:10

فَٱرْتَقِبْ يَوْمَ تَأْتِى ٱلسَّمَآءُ بِدُخَانٍ مُّبِينٍ

fa-irtaqib yawma tatī l-samāʾu bi-dukhānin mubīnin

إِنَّا مُرْسِلُوا۟ ٱلنَّاقَةِ فِتْنَةً لَّهُمْ فَٱرْتَقِبْهُمْ وَٱصْطَبِرْ

innā mursilū l-nāqati fitnatan lahum fa-irtaqibhum wa-iṣṭabir

For We will send the she-camel by way of trial for them. So watch them, (O Salih), and possess thyself in patience!
