Quran 17:7 from Surah Al-Israa on Divine Marvels.
إِنۡ أَحۡسَنتُمۡ أَحۡسَنتُمۡ لِأَنفُسِكُمۡۖ وَإِنۡ أَسَأۡتُمۡ فَلَهَاۚ فَإِذَا جَآءَ وَعۡدُ ٱلۡأٓخِرَةِ لِيَسُـُٔواْ وُجُوهَكُمۡ وَلِيَدۡخُلُواْ ٱلۡمَسۡجِدَ كَمَا دَخَلُوهُ أَوَّلَ مَرَّةٖ وَلِيُتَبِّرُواْ مَا عَلَوۡاْ تَتۡبِيرًا
English translation: If you do good you do good for yourselves and if you do evil then it is for it So when came promise the last to sadden your faces and to enter the Masjid just as they (had) entered it first time and to destroy what they had conquered (with) destruction
Transliteration: in ahsantum ahsantum li-anfusikum wa-in asatum falaha fa-idha jaa wa'du al-akhirati liyasuu wujuhakum waliyadkhulu al-masjida kama dakhaluhu awwala marratin waliyutabbiru ma alaw tatbiran
