Sura al-Baqara 2:276

يَمْحَقُ ٱللَّـهُ ٱلرِّبَوٰا۟ وَيُرْبِى ٱلصَّدَقَٰتِ وَٱللَّـهُ لَا يُحِبُّ كُلَّ كَفَّارٍ أَثِيمٍ

yamḥaqu allāhu l-ribā wa-yurbī l-ṣadaqāti wallāhu lā yuḥibbu kulla kaffārin athīmin

Allah will deprive usury of all blessing, but will give increase for deeds of charity: For He loveth not creatures ungrateful and wicked.

Sura al-Naḥl 16:92

وَلَا تَكُونُوا۟ كَٱلَّتِى نَقَضَتْ غَزْلَهَا مِنۢ بَعْدِ قُوَّةٍ أَنكَٰثًا تَتَّخِذُونَ أَيْمَٰنَكُمْ دَخَلًۢا بَيْنَكُمْ أَن تَكُونَ أُمَّةٌ هِىَ أَرْبَىٰ مِنْ أُمَّةٍ إِنَّمَا يَبْلُوكُمُ ٱللَّـهُ بِهِۦ وَلَيُبَيِّنَنَّ لَكُمْ يَوْمَ ٱلْقِيَٰمَةِ مَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

wa-lā takūnū ka-llatī naqaḍat ghazlahā min baʿdi quwwatin ankāthan tattakhidhūna aymānakum dakhalan baynakum an takūna ummatun hiya arba min ummatin innamā yablūkumu allāhu bihi wa-layubayyinanna la-kum yawma l-qiyāmati mā kuntum fīhi takhtalifūna

And be not like a woman who breaks into untwisted strands the yarn which she has spun, after it has become strong. Nor take your oaths to practise deception between yourselves, lest one party should be more numerous than another: for Allah will test you by this; and on the Day of Judgment He will certainly make clear to you (the truth of) that wherein ye disagree.
