Description: Imam Ali (a.s.) said in his intimate supplication, ‘My God, I have no way to guard myself from sin except through Your protection, and no way to attain good deeds except by Your will. So how can I ever benefit from that which You have preceded with Your will! And how can I ever guard myself from sins as long as Your protection does not cover me therein!’
الإمامُ عليٌ (عَلَيهِ الّسَلامُ) ـ في مُناجاتِهِ ـ: إلهي ، لا سَبيلَ إلي الاحتِراسِ مِنَ الذَّنبِ إلّا بِعِصمَتِكَ ، ولا وُصولَ إلي عَمَلِ الخَيراتِ إلّا بِمَشِيئَتِكَ ، فكَيفَ لي بِإفادَةِ ما أسلَفتَني فيهِ مَشيئَتَكَ ؟! وكَيفَ لي بِالاحتِراسِ مِنَ الذَّنبِ ما إن لَم تُدرِكْني فيهِ عِصمَتُكَ؟!
