Surah Al-Isra, ayah 7

17:7

إِنۡ أَحۡسَنتُمۡ أَحۡسَنتُمۡ لِأَنفُسِكُمۡۖ وَإِنۡ أَسَأۡتُمۡ فَلَهَاۚ فَإِذَا جَآءَ وَعۡدُ ٱلۡأٓخِرَةِ لِيَسُـُٔواْ وُجُوهَكُمۡ وَلِيَدۡخُلُواْ ٱلۡمَسۡجِدَ كَمَا دَخَلُوهُ أَوَّلَ مَرَّةٖ وَلِيُتَبِّرُواْ مَا عَلَوۡاْ تَتۡبِيرًا ٧

In ahsantum ahsantum li anfusikum wa in asa'tum falahā fa idhā jā'a wa'dul-ākhirati liyasu'ū wujūhakum waliyadkhulul-masjida kamā dakhalūhu awwala marratin waliyutabbirū mā 'alaw tatbīrā

[And said], "If you do good, you do good for yourselves; and if you do evil, [you do it] to them [i.e., yourselves]." Then when the final [i.e., second] promise came, [We sent your enemies] to sadden your faces and to enter the masjid [i.e., the temple in Jerusalem], as they entered it the first time, and to destroy what they had taken over with [total] destruction.
