يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ
Allah keeps those who believe firm through the firm word in worldly life and in the Hereafter. (Ibrahim 14:27)
Al-qawl al-thabit denotes the firm word of faith. The verse affirms steadfastness in this world and its benefit in the Hereafter. The believer's firmness when questioned in the grave is explained through this promise.
