﴿يَوْمَ لاَ يُخْزِى اللَّهُ النَّبِىَّ وَالَّذِينَ ءَامَنُواْ مَعَهُ نُورُهُمْ يَسْعَى بَيْنَ أَيْدِيهِمْ وَبِأَيْمَـنِهِمْ يَقُولُونَ رَبَّنَآ أَتْمِمْ لَنَا نُورَنَا وَاغْفِرْ لَنَآ إِنَّكَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ﴾
(The Day that Allah will not disgrace the Prophet (Muhammad ) and those who believe with him. Their Light will run forward before them and (with their Records ـ Books of deeds) in their right hands. They will say: "Our Lord! Keep perfect our Light for us ﴿and do not put it off till we cross over the Sirat (a slippery bridge over the Hell) safely﴾ and grant us forgiveness. Verily, You are Able to do all things'') (66:8).
Ibn Abi Hatim narrated that `Abdullah bin Mas`ud commented on,
﴿نُورُهُمْ يَسْعَى بَيْنَ أَيْدِيهِمْ﴾
(Their Light will run forward before them), "They will pass on the Sirat. according to their deeds. The light that some people have will be as big as a mountain, while the light of others will be as big as a date tree. The people who will have the least light are those whose index fingers will sometimes be lit and extinguished at other times.'' Ibn Abi Hatim also reported that Ibn `Abbas said, "Every person among the people of Tawhid (Islamic Monotheism) will gain a light on the Day of Resurrection. As for the hypocrite, his light will be extinguished.
Abdullah bin `Amr said that the Prophet said,
«ثَلَاثٌ مَنْ كُنَّ فِيهِ كَانَ مُنَافِقًا خَالِصًا، وَمَنْ كَانَتْ فِيهِ وَاحِدَةٌ مِنْهُنَّ كَانَتْ فِيهِ خَصْلَةٌ مِنَ النِّفَاقِ حَتَّى يَدَعَهَا: مَنْ إِذَا حَدَّثَ كَذَبَ، وَإِذَا وَعَدَ أَخْلَفَ، وَإِذَا ائْتُمِنَ خَان»
(Whoever has the following three (characteristics) will be a pure hypocrite, and whoever has one of the following three characteristics will have one characteristic of hypocrisy, unless and until he gives it up. Whenever he speaks, he tells a lie. Whenever he makes a covenant, he proves treacherous. Whenever he is entrusted, he breaches the trust)
Hence, man might have both a part of faith and a part of hypocrisy, whether in deed, as this Hadith stipulates, or in the creed, as the Ayah (2:20) stipulates.
