2:143
وَكَذَلِكَ جَعَلْنَاكُمْ أُمَّةً وَسَطاً لِّتَكُونُواْ شُهَدَاء عَلَى النَّاسِ وَيَكُونَ الرَّسُولُ عَلَيْكُمْ شَهِيداً وَمَا جَعَلْنَا الْقِبْلَةَ الَّتِي كُنتَ عَلَيْهَا إِلاَّ لِنَعْلَمَ مَن يَتَّبِعُ الرَّسُولَ مِمَّن يَنقَلِبُ عَلَى عَقِبَيْهِ وَإِن كَانَتْ لَكَبِيرَةً إِلاَّ عَلَى الَّذِينَ هَدَى اللّهُ وَمَا كَانَ اللّهُ لِيُضِيعَ إِيمَانَكُمْ إِنَّ اللّهَ بِالنَّاسِ لَرَؤُوفٌ رَّحِيمٌ
Thus, have We made of you an Ummat justly balanced, that ye might be witnesses over the nations, and the Messenger a witness over yourselves; and We appointed the Qibla to which thou wast used, only to test those who followed the Messenger from those who would turn on their heels (From the Faith). Indeed it was (A change) momentous, except to those guided by Allah. And never would Allah Make your faith of no effect. For Allah is to all people Most surely full of kindness, Most Merciful.
25:67
وَالَّذِينَ إِذَا أَنفَقُوا لَمْ يُسْرِفُوا وَلَمْ يَقْتُرُوا وَكَانَ بَيْنَ ذَلِكَ قَوَاماً
Those who, when they spend, are not extravagant and not niggardly, but hold a just (balance) between those (extremes);
