إِن تَمْسَسْكُمْ حَسَنَةٌ تَسُؤْهُمْ وَإِن تُصِبْكُمْ سَيِّئَةٌ يَفْرَحُوا بِهَا وَإِن تَصْبِرُوا وَتَتَّقُوا لَا يَضُرُّكُمْ كَيْدُهُمْ شَيْئًا إِنَّ اللَّهَ بِمَا يَعْمَلُونَ مُحِيطٌ ١٢٠

يَفْرَحُوا yafraḥū · they rejoice

If good touches you, it distresses them; but if harm strikes you, they rejoice at it. And if you are patient and fear Allāh, their plot will not harm you at all. Indeed, Allāh is encompassing of what they do. (Surah Ali 'Imran, 3:120)

لَا تَحْسَبَنَّ الَّذِينَ يَفْرَحُونَ بِمَا أَتَوا وَّيُحِبُّونَ أَن يُحْمَدُوا بِمَا لَمْ يَفْعَلُوا فَلَا تَحْسَبَنَّهُم بِمَفَازَةٍ مِّنَ الْعَذَابِ وَلَهُمْ عَذَابٌ أَلِيمٌ ١٨٨

يَفْرَحُونَ yafraḥūna · rejoice

And never think that those who rejoice in what they have perpetrated and like to be praised for what they did not do - never think them [to be] in safety from the punishment, and for them is a painful punishment. (Surah Ali 'Imran, 3:188)

فَرِحِينَ بِمَا آتَاهُمُ اللَّهُ مِن فَضْلِهِ وَيَسْتَبْشِرُونَ بِالَّذِينَ لَمْ يَلْحَقُوا بِهِم مِّنْ خَلْفِهِمْ أَلَّا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ ١٧٠

فَرِحِينَ fariḥīna · Rejoicing

Rejoicing in what Allāh has bestowed upon them of His bounty, and they receive good tidings about those [to be martyred] after them who have not yet joined them - that there will be no fear concerning them, nor will they grieve. (Surah Ali 'Imran, 3:170)
