Sura al-Naḥl 16:19

وَٱللَّـهُ يَعْلَمُ مَا تُسِرُّونَ وَمَا تُعْلِنُونَ

wallāhu yaʿlamu mā tusirrūna wa-mā tuʿlinūna

And Allah doth know what ye conceal, and what ye reveal.

Sura al-Naml 27:25

أَلَّا يَسْجُدُوا۟ لِلَّـهِ ٱلَّذِى يُخْرِجُ ٱلْخَبْءَ فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَيَعْلَمُ مَا تُخْفُونَ وَمَا تُعْلِنُونَ

allā yasjudū lillāhi alladhī yukhriju l-khaba fī l-samāwāti wa-l-arḍi wa-yaʿlamu mā tukhfūna wa-mā tuʿlinūna

"(Kept them away from the Path), that they should not worship Allah, Who brings to light what is hidden in the heavens and the earth, and knows what ye hide and what ye reveal.

Sura al-Mumtaḥanah 60:1

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ عَدُوِّى وَعَدُوَّكُمْ أَوْلِيَآءَ تُلْقُونَ إِلَيْهِم بِٱلْمَوَدَّةِ وَقَدْ كَفَرُوا۟ بِمَا جَآءَكُم مِّنَ ٱلْحَقِّ يُخْرِجُونَ ٱلرَّسُولَ وَإِيَّاكُمْ أَن تُؤْمِنُوا۟ بِٱللَّـهِ رَبِّكُمْ إِن كُنتُمْ خَرَجْتُمْ جِهَٰدًا فِى سَبِيلِى وَٱبْتِغَآءَ مَرْضَاتِى تُسِرُّونَ إِلَيْهِم بِٱلْمَوَدَّةِ وَأَنَا۠ أَعْلَمُ بِمَآ أَخْفَيْتُمْ وَمَآ أَعْلَنتُمْ وَمَن يَفْعَلْهُ مِنكُمْ فَقَدْ ضَلَّ سَوَآءَ ٱلسَّبِيلِ

yā-ayyuhā lladhīna āmanū lā tattakhidhū ʿaduwwī wa-ʿaduwwakum awliyāʾa tulqūna ilayhim bil-mawaddati wa-qad kafarū bi-mā jāʾakum mina l-ḥaqqi yukhrijūna l-rasūla wa-iyyākum an tūʾminū billāhi rabbikum in kuntum kharajtum jihādan fī sabīlī wa-ibtighāʾa marḍātī tusirrūna ilayhim bil-mawaddati wa-anā aʿlamu bimā akhfaytum wa-mā aʿlantum wa-man yafʿalhu minkum fa-qad ḍalla sawāʾa l-sabīli

O ye who believe! Take not my enemies and yours as friends (or protectors),- offering them (your) love, even though they have rejected the Truth that has come to you, and have (on the contrary) driven out the Prophet and yourselves (from your homes), (simply) because ye believe in Allah your Lord! If ye have come out to strive in My Way and to seek My Good Pleasure, (take them not as friends), holding secret converse of love (and friendship) with them: for I know full well all that ye conceal and all that ye reveal. And any of you that does this has strayed from the Straight Path.

Sura al-Taghābun 64:4

يَعْلَمُ مَا فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَيَعْلَمُ مَا تُسِرُّونَ وَمَا تُعْلِنُونَ وَٱللَّـهُ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ

yaʿlamu mā fī l-samāwāti wa-l-arḍi wa-yaʿlamu mā tusirrūna wa-mā tuʿlinūna wallāhu ʿalīmun bi-dhāti l-ṣudūri

He knows what is in the heavens and on earth; and He knows what ye conceal and what ye reveal: yea, Allah knows well the (secrets) of (all) hearts.
