Imam Hussain said in one of his supplications: “It is You who removed strangers from the hearts of Your lovers so that they never love other than You…What does the one who loses You find [besides You]?! And what does the one who finds You lose [out on]?! He indeed fails who is satisfied with a substitute for You.”

الإمامُ الحسينُ (عَلَيهِ الّسَلامُ) ـ في الدعاء المنسوب إليه ـ: أنتَ الّذي أزَلْتَ الأغْيارَ عن قُلوبِ أحِبّائكَ حتّى لَم يُحِبّوا سِواكَ... ماذا وَجَدَ مَن فَقَدَكَ؟! وما الّذي فَقَد مَن وَجَدكَ؟! لَقد خابَ مَن ‏رَضِيَ دُونَكَ بَدَلاً.
