The Quran root س ر ر s-r-r

أَوَلَا يَعْلَمُونَ أَنَّ اللَّهَ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ ٧٧

يُسِرُّونَ yusirrūna · they conceal

But do they not know that Allāh knows what they conceal and what they declare? (Surah Al-Baqarah, 2:77)

فَتَرَى الَّذِينَ فِي قُلُوبِهِم مَّرَضٌ يُسَارِعُونَ فِيهِمْ يَقُولُونَ نَخْشَىٰ أَن تُصِيبَنَا دَائِرَةٌ فَعَسَى اللَّهُ أَن يَأْتِيَ بِالْفَتْحِ أَوْ أَمْرٍ مِّنْ عِندِهِ فَيُصْبِحُوا عَلَىٰ مَا أَسَرُّوا فِي أَنفُسِهِمْ نَادِمِينَ ٥٢

أَسَرُّوا asarrū · they had concealed

So you see those in whose hearts is disease [i.e., hypocrisy] hastening into [association with] them, saying, "We are afraid a misfortune may strike us." But perhaps Allāh will bring conquest or a decision from Him, and they will become, over what they have been concealing within themselves, regretful. (Surah Al-Ma'idah, 5:52)

وَلَا جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُم بِهِ مِنْ خِطْبَةِ النِّسَاءِ أَوْ أَكْنَنتُمْ فِي أَنفُسِكُمْ عَلِمَ اللَّهُ أَنَّكُمْ سَتَذْكُرُونَهُنَّ وَلَٰكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّا أَن تَقُولُوا قَوْلًا مَّعْرُوفًا وَلَا تَعْزِمُوا عُقْدَةَ النِّكَاحِ حَتَّىٰ يَبْلُغَ الْكِتَابُ أَجَلَهُ وَاعْلَمُوا أَنَّ اللَّهَ يَعْلَمُ مَا فِي أَنفُسِكُمْ فَاحْذَرُوهُ وَاعْلَمُوا أَنَّ اللَّهَ غَفُورٌ حَلِيمٌ ٢٣٥

سِرًّا sirran · secretly

There is no blame upon you for that to which you [indirectly] allude concerning a proposal to women or for what you conceal within yourselves. Allāh knows that you will have them in mind. But do not promise them secretly except for saying a proper saying. And do not determine to undertake a marriage contract until the decreed period reaches its end. And know that Allāh knows what is within yourselves, so beware of Him. And know that Allāh is Forgiving and Forbearing. (Surah Al-Baqarah, 2:235)

وَنَزَعْنَا مَا فِي صُدُورِهِم مِّنْ غِلٍّ إِخْوَانًا عَلَىٰ سُرُرٍ مُّتَقَابِلِينَ ٤٧

سُرُرٍ sururin · thrones

And We will remove whatever is in their breasts of resentment, [so they will be] brothers, on thrones facing each other. (Surah Al-Hijr, 15:47)

الَّذِينَ يُنفِقُونَ فِي السَّرَّاءِ وَالضَّرَّاءِ وَالْكَاظِمِينَ الْغَيْظَ وَالْعَافِينَ عَنِ النَّاسِ وَاللَّهُ يُحِبُّ الْمُحْسِنِينَ ١٣٤

السَّرَّاءِ l-sarāi · [the] ease

Who spend [in the cause of Allāh] during ease and hardship and who restrain anger and who pardon the people - and Allāh loves the doers of good; (Surah Ali 'Imran, 3:134)

ذَٰلِكَ بِأَنَّهُمْ قَالُوا لِلَّذِينَ كَرِهُوا مَا نَزَّلَ اللَّهُ سَنُطِيعُكُمْ فِي بَعْضِ الْأَمْرِ وَاللَّهُ يَعْلَمُ إِسْرَارَهُمْ ٢٦

إِسْرَارَهُمْ is'rārahum · their secrets

That is because they said to those who disliked what Allāh sent down, "We will obey you in part of the matter." And Allāh knows what they conceal. (Surah Muhammad, 47:26)
