قَالَ النَّبِيُّ ﷺ وَ اَخَذَ بِيَدِ عَلِيٍّ ؑ مَنْ زَعَمَ اَنَّهٗ يُحِبُّنِي وَ لَا يُحِبُّ هٰذَا فَقَدْ كَذَبَ
The Holy Prophet (peace be on him and his progeny) took the hand of Ali (peace be on him) and declared,
“Whoever thinks that he loves me but does not love him (viz. Ali) then indeed he has lied.”
