4ـ أَحْمَدُ بْنُ مُحَمَّدٍ الْكُوفِيُّ عَنْ عَلِيِّ بْنِ الْحَسَنِ التَّيْمِيِّ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ يَعْقُوبَ بْنِ سَالِمٍ قَالَ كُنْتُ عِنْدَ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) فَقَالَ لَهُ الْعَلاءُ بْنُ كَامِلٍ إِنَّ فُلاناً يَفْعَلُ بِي وَيَفْعَلُ فَإِنْ رَأَيْتَ أَنْ تَدْعُوَ الله عَزَّ وَجَلَّ فَقَالَ هَذَا ضَعْفٌ بِكَ قُلِ اللهمَّ إِنَّكَ تَكْفِي مِنْ كُلِّ شَيْ‏ءٍ وَلا يَكْفِي مِنْكَ شَيْ‏ءٌ فَاكْفِنِي أَمْرَ فُلانٍ بِمَ شِئْتَ وَكَيْفَ شِئْتَ وَمِنْ حَيْثُ شِئْتَ وَأَنَّى شِئْتَ.

4. Ahmad ibn Muhammad al-Kufi has narrated from Ali ibn al-Hassan al-Taymi from Ali ibn Asbat from Ya’qub ibn Salim who has said the following: “Once I was in the presence of abu ‘Abd Allah (a.s.) and al-‘Ala’ ibn Kamil said to him, ‘So and so acts against me again and again, if you consider it proper, pray to Allah, the Most Majestic, the Most Holy.’ The Imam said, ‘This is more than enough for you. Say, “O Lord, You are sufficient for everything and nothing is sufficient for You. Suffice me in the matters of so and so with whatever You wish, in whatever way You wish, from wherever You wish and whenever You wish.’”
