The Guide (from Allah-azwj)
رُوِيَ عَنِ ابْنِ عَبَّاسٍ أَنَّهُ قَالَ: لَمَّا نَزَلَتِ الْآيَةُ قَالَ رَسُولُ اللَّهِ ص أَنَا الْمُنْذِرُ وَ عَلِيٌّ الْهَادِي مِنْ بَعْدِي يَا عَلِيُّ بِكَ يَهْتَدِي الْمُهْتَدُونَ
It is reported from Ibn Abbas having said, ‘When the Verse was Revealed, Rasool-Allah-saww said: ‘I-saww am the warner and Ali-asws is the guide from after me-saww. O Ali-asws! Through you-asws the guided ones are guided’’.[1]
