Surah Al-Mu'minun, Verse 100

لَعَلِّيٓ أَعۡمَلُ صَٰلِحٗا فِيمَا تَرَكۡتُۚ كـَلَّآۚ إِنَّهَا كَلِمَةٌ هُوَ قَآئِلُهَاۖ وَمِن وَرَآئِهِم بَرۡزَخٌ إِلَىٰ يَوۡمِ يُبۡعَثُونَ١٠٠

laʿallī aʿmalu ṣāliḥan fīmā taraktu kallā innahā kalimatun huwa qāiluhā wamin warāihim barzakhun ilā yawmi yub'ʿathūna

That I might do righteousness in that which I left behind." No! It is only a word he is saying; and behind them is a barrier until the Day they are resurrected.
