وَٱلَّذِينَ يُمَسِّكُونَ بِٱلۡكِتَٰبِ وَأَقَامُواْ ٱلصَّلَوٰةَ إِنَّا لَا نُضِيعُ أَجۡرَ ٱلۡمُصۡلِحِينَ ١٧٠
But those who hold fast to the Book [i.e., the Qur’ān] and establish prayer - indeed, We will not allow to be lost the reward of the reformers.
Translation: Saheeh International (English)
Each word's meaning and sound
Those who hold tightly to the scripture and act according to it, establishing the prayer as it should be established and in its set times, Allah will reward their actions – Allah does not allow the reward of those who act well to be lost.
