The Coloring (referred to in the Holy Quran) Is Islam
3 Aḥadīth
Ali ibn Ibrahim has narrated from his father and Muhammad ibn Yahya from Ahmad ibn Muhammad all from ibn Mahbub from ‘Abd Allah ibn Sinan from Abu ‘Abdillah 
who has said the following: “About the words of Allah, the Majestic, the Glorious, ‘. . . It is the coloring of Allah. Who has a better color than Allah’s color?’ (2:138), Abu ‘Abdillah said, ‘Color is a reference to this belief.’ The Imam also said, ‘It (color) stands for al-Islam.’ In the words of Allah, the Majestic, the Glorious, ‘. . . He has established a firm hold onto the strong ring’. . . (2:256), he said, ‘It (the strong ring) is a reference to the faith and belief in Allah, Who is One and has no partners.’”
عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) فِي قَوْلِ الله عَزَّ وَجَلَّ صِبْغَةَ الله وَمَنْ أَحْسَنُ مِنَ الله صِبْغَةً قَالَ الإسْلامُ وَقَالَ فِي قَوْلِهِ عَزَّ وَجَلَّ فَقَدِ اسْتَمْسَكَ بِالْعُرْوَةِ الْوُثْقى قَالَ هِيَ الإيمَانُ بِالله وَحْدَهُ لا شَرِيكَ لَهُ.

عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ دَاوُدَ بْنِ سِرْحَانَ عَنْ عَبْدِ الله بْنِ فَرْقَدٍ عَنْ حُمْرَانَ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) فِي قَوْلِ الله عَزَّ وَجَلَّ صِبْغَةَ الله وَمَنْ أَحْسَنُ مِنَ الله صِبْغَةً قَالَ الصِّبْغَةُ هِيَ الإسْلامُ.

حُمَيْدُ بْنُ زِيَادٍ عَنِ الْحَسَنِ بْنِ مُحَمَّدِ بْنِ سَمَاعَةَ عَنْ غَيْرِ وَاحِدٍ عَنْ أَبَانٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَحَدِهِمَا (عَلَيهِما السَّلام) فِي قَوْلِ الله عَزَّ وَجَلَّ صِبْغَةَ الله وَمَنْ أَحْسَنُ مِنَ الله صِبْغَةً قَالَ الصِّبْغَةُ هِيَ الإسْلامُ وَقَالَ فِي قَوْلِهِ عَزَّ وَجَلَّ فَمَنْ يَكْفُرْ بِالطَّاغُوتِ وَيُؤْمِنْ بِالله فَقَدِ اسْتَمْسَكَ بِالْعُرْوَةِ الْوُثْقى قَالَ هِيَ الإيمَانُ.
