Allaah (The Most High) said:

فَأَقۡبَلَ بَعۡضُہُمۡ عَلَىٰ بَعۡضٍ۬ يَتَسَآءَلُونَ

قَالَ قَآٮِٕلٌ۬ مِّنۡہُمۡ إِنِّى كَانَ لِى قَرِينٌ۬

يَقُولُ أَءِنَّكَ لَمِنَ ٱلۡمُصَدِّقِينَ

أَءِذَا مِتۡنَا وَكُنَّا تُرَابً۬ا وَعِظَـٰمًا أَءِنَّا لَمَدِينُونَ

قَالَ هَلۡ أَنتُم مُّطَّلِعُونَ

فَٱطَّلَعَ فَرَءَاهُ فِى سَوَآءِ ٱلۡجَحِيمِ

قَالَ تَٱللَّهِ إِن كِدتَّ لَتُرۡدِينِ

وَلَوۡلَا نِعۡمَةُ رَبِّى لَكُنتُ مِنَ ٱلۡمُحۡضَرِينَ

Then they (i.e. the people of paradise) will turn to one another, mutually questioning. A speaker of them will say: “Verily, I had a companion (in the world), Who used to say: “Are you among those who believe (in resurrection after death). (That) when we die and become dust and bones, shall we indeed (be raised up) to receive reward or punishment (according to our deeds)? (The man) said: “Will you look down? So he looked down and saw him in the midst of the Fire. He said: “By Allah! You have nearly ruined me. Had it not been for the Grace of my Lord, I would certainly have been among those brought forth (to Hell).” [37:50-57]
