Sura al-Anʿām 6:63

قُلْ مَن يُنَجِّيكُم مِّن ظُلُمَٰتِ ٱلْبَرِّ وَٱلْبَحْرِ تَدْعُونَهُۥ تَضَرُّعًا وَخُفْيَةً لَّئِنْ أَنجَىٰنَا مِنْ هَٰذِهِۦ لَنَكُونَنَّ مِنَ ٱلشَّٰكِرِينَ

qul man yunajjīkum min ẓulumāti l-barri wa-l-baḥri tadʿūnahu taḍarruʿan wa-khufyatan la-in anjānā min hādhihi la-nakūnanna mina l-shākirīna

Say: "Who is it that delivereth you from the dark recesses of land and sea, when ye call upon Him in humility and silent terror: 'If He only delivers us from these (dangers), (we vow) we shall truly show our gratitude'?"

Sura al-Aʿrāf 7:55

ٱدْعُوا۟ رَبَّكُمْ تَضَرُّعًا وَخُفْيَةً إِنَّهُۥ لَا يُحِبُّ ٱلْمُعْتَدِينَ

idʿū rabbakum taḍarruʿan wa-khufyatan innahu lā yuḥibbu l-muʿtadīna

Call on your Lord with humility and in private: for Allah loveth not those who trespass beyond bounds.

Sura al-Raʿd 13:10

سَوَآءٌ مِّنكُم مَّنْ أَسَرَّ ٱلْقَوْلَ وَمَن جَهَرَ بِهِۦ وَمَنْ هُوَ مُسْتَخْفٍۭ بِٱلَّيْلِ وَسَارِبٌۢ بِٱلنَّهَارِ

sawāʾun minkum man asarra l-qawla wa-man jahara bihi wa-man huwa mustakhfin bil-layli wa-sāribun bil-nahāri

It is the same (to Him) whether any of you conceal his speech or declare it openly; whether he lie hid by night or walk forth freely by day.

Sura Ṭā Hā 20:7

وَإِن تَجْهَرْ بِٱلْقَوْلِ فَإِنَّهُۥ يَعْلَمُ ٱلسِّرَّ وَأَخْفَى

wa-in tajhar bil-qawli fa-innahu yaʿlamu l-sirra wa-akhfa

If thou pronounce the word aloud, (it is no matter): for verily He knoweth what is secret and what is yet more hidden.

Sura al-Ḥāqqah 69:18

يَوْمَئِذٍ تُعْرَضُونَ لَا تَخْفَىٰ مِنكُمْ خَافِيَةٌ

yawmaʾidhin tuʿraḍūna lā takhfā minkum khāfiyatun

That Day shall ye be brought to Judgment: not an act of yours that ye hide will be hidden.
