Martyrdom of Imam Ali - Amir al-Mu'minin (PBUH) : The Principle of Oath Keeping 

 In the Name of Allah, the Beneficent, the Merciful



The Principle of Oath Keeping

The principle of oath keeping is considered one of the highest virtues in Islam. The teachings of the Holy Quran and the Ahl al-Bayt (PBUT) regard oath keeping as a fundamental requirement of faith (1); where neglecting one’s oath has been considered alongside irreligiousness and faithlessness. (2)

This principle does not pertain solely to relations between members of the religious community; they are responsible to observe this faith-oriented, yet humanistic rule also in respect to non-Muslims whether they be friends or enemies. As evident in the life of the Holy Prophet (PBUH&HP), history shows us the many oaths the Prophet made and kept with the pagans, Christians of Najran, and other Arab tribes.

Islamic teachings about observing one’s oath are innumerous. The following account is the order of Imam Ali (PBUH) to his commander in Egypt.

The letter, which is known as “the Malik Ashtar letter of oath” is an example of the glorious thoughts and ideas of Amir al-Mu'minin (PBUH). The points made in this letter are said with such detail and depth that one can say, they can accommodate the responsibility of all mankind towards the creator, whether it be as a person in any society, as a leader who carries out laws of the Islam, or as a person who lives under an Islamic government.  

Although Imam Ali (PBUH) has addressed Malik Ashtar in the letter, the concepts can be applied to every human being across the world, past and present. Let us now review parts of the letter.

“If you made an oath with an enemy, or showed him mercy, keep your oath and put your life as a guarantee to it.

Preserving one’s oath and promise is a divine principle strongly accepted by all mankind.  For pagans, just as Muslims, the observing of oath was also very important, for they had experienced the horrible consequences of breaking oaths. Therefore, never break your oaths and never betray your vows, and don’t betray your enemy whom you have made an oath with. For, no one shows arrogance towards Allah (SWT) except the miserable ignorant.  

The Almighty has designated His oath as a guarantee, and from His blessings has made its observance a responsibility on all his servants. An Oath and an allegiance is a safe haven so people can be reassured to its persistence, and for all to choose as a haven. Trickery and betrayal is not permissible in any oath. Never make an oath with unclear content, and once emphasis and strong statements have been made, do not use vague and two-sided phrases [to make it irrelevant.]

Beware the difficulty of an oath and your pledge to Allah (SWT) that you have made does not entice you to void it through wrong means. For your patience during the hardships of an oath and pledge to Allah (SWT) for which you have hopes for its outcome is better than the betrayal and disloyalty that you fear its consequences. The same disloyalty that will incite one’s divine responsibility to such that he/she will be unable to answer for in this world or the hereafter. (3)
