Al A'raf, 170 Ayah
7:170
وَٱلَّذِينَ يُمَسِّكُونَ بِٱلۡكِتَٰبِ وَأَقَامُواْ ٱلصَّلَوٰةَ إِنَّا لَا نُضِيعُ أَجۡرَ ٱلۡمُصۡلِحِينَ ١٧٠
Wa Al-Ladhīna Yumassikūna Bil-Kitābi Wa 'Aqāmū Aş-Şalāata 'Innā Lā Nuđī`u 'Ajra Al-Muşliĥīna
But those who hold fast to the Book and establish prayer - indeed, We will not allow to be lost the reward of the reformers.
