3ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : اعتَصِموا (استَعصِموا) بالذِّمَمِ في أوْتادِها.
3- Imam Ali (AS) said, ‘Adhere to sureties [that you are liable for] in all firmness.’[Nahj al-Balagha, Saying 155]
4ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) ـ في عَهدهِ للأشتَرِ ـ : وإنْ عَقَدتَ بينَكَ وبينَ عدُوِّكَ عُقْدةً أو ألْبَسْتَهُ مِنكَ ذِمّةً فَحُطْ عهدَكَ بالوفاءِ وَارعَ ذمَّتَك بالأمانَةِ، واجعَلْ نفسَكَ جُنّةً دُونَ ما أعطَيتَ، فإنّهُ ليسَ مِن فرائضِ اللّهِ شَيءٌ النّاسُ أشَدُّ علَيهِ اجْتِماعاً مَعتَفرُّقِ أهوائِهم وتَشتُّتِ آرائهِم مِن تعظيمِ الوفاءِ بالعُهودِ.
4- Imam Ali (AS) said, in his epistle to MÁlik al-Ashtar: ‘And if you make a covenant between yourself and your enemy or give him a surety [against life or property], then stand by your pact with loyalty and observe your liability with trustworthiness. Make yourself the shield for your word, for there is nothing from Allah’s mandates that all people agree upon, despite their diverse opinions on everything else, as much as they do with regards to respecting the fulfilment of covenants.’[Ibid. Letter 53]
