So today no ransom will be taken from you or from those who disbelieved. Your refuge is the Fire. It is most worthy of you, and wretched is the destination."
The Believers are awarded a Light on the Day of Resurrection, according to Their Good Deeds
Allah the Exalted states that the believers who spend in charity will come on the Day of Resurrection with their light preceding them in the area of the Gathering, according to the level of their good deeds. As reported from `Abdullah bin Mas`ud:
يَسْعَى نُورُهُم بَيْنَ أَيْدِيهِمْ
(their light running forward before them), he said, "They will pass over the Sirat according to their deeds. Some of them will have a light as large as a mountain, some as a date tree, some as big as a man in the standing position. The least among them has a light as big as his index finger, it is lit at times and extinguished at other times." Ibn Abi Hatim and Ibn Jarir collected this Hadith. Ad-Dahhak commented on the Ayah, "Everyone will be given a light on the Day of Resurrection. When they arrive at the Sirat, the light of the hypocrites will be extinguished. When the believers see this, they will be concerned that their light also will be extinguished, just as the light of the hypocrites was. This is when the believers will invoke Allah, `O our Lord! Perfect our light for us."' Allah's statement,
يَوْمَ يَقُولُ الْمُنَافِقُونَ وَالْمُنَافِقَاتُ لِلَّذِينَ آمَنُوا انظُرُونَا نَقْتَبِسْ مِن نُّورِكُمْ (...the Day when the hypocrite men and hypocrite women will say to those who believe, "Wait for us, so that we may have a share from your light...(57:13) The meaning is self-evident.
قِيلَ ارْجِعُوا وَرَاءَكُمْ فَالْتَمِسُوا نُورًا (...it will be said [ to them ], "Go back to your rear, and search for light ....57:13) This reply will be given by either the believers, or by the angels. [ Ibn ` Abbas ؓ and Qatadah (رح) ]
فَضُرِبَ بَيْنَهُم بِسُورٍ لَّهُ بَابٌ بَاطِنُهُ فِيهِ الرَّحْمَةُ وَظَاهِرُهُ مِن قِبَلِهِ الْعَذَابُ (...Then a wall will be placed between them, which will have a gate. In its inner side, there will be the Divine mercy, while towards its outer side, there will be the Divine punishment...57:13). Having received the reply from either the believers or the angels, the hypocrites will return to the place where the light was distributed. They will find nothing there, so they will attempt to go back to the believers but in the meantime a wall will be set up between the hypocrites and the believers. As a result, the hypocrites will be separated from the believers and will not be able to reach them. They will be left in complete darkness. On the side of the believers there will be Allah's mercy while on the side of the hypocrites there will be chastisement.
While Islam was still unfamiliar, accepting it meant putting oneself through a great trial. At that time, the truth of Islam was veiled in doubt. Spending for Islam at that time was like giving a loan to somebody with flimsy hopes of getting any return. The atmosphere was pervaded by doubt and hesitation. As compared to the promises of God, the benefits right before people appear more certain to them. Under these circumstances, surrendering one’s life and property for the cause of Islam requires a very strong decision-making ability. At such a time, only one who has the capacity to recognise the reality of things through wisdom and insight, has the courage to progress in the right direction. For those who prove to have this insight in the world, it will become easy on the Day of Judgement; by making use of their insight, they will be able to pass more easily through the difficult stages there. The insight which had become their guide in this world will, by the grace of God, serve as a guide also in the Hereafter.
