اقرأ وتدبر الآية 4353 من سورة سُورَةُ الزُّخۡرُفِ: وَجَعَلَهَا كَلِمَةً بَاقِيَةً فِي عَقِبِهِ لَعَلَّهُمْ يَرْجِعُونَ
وَجَعَلَهَا كَلِمَةً بَاقِيَةً فِي عَقِبِهِ لَعَلَّهُمْ يَرْجِعُونَ
And he uttered this as a word destined to endure among those who would come after him, so that they might [always] return [to it].
