The dua against enemies calls upon Allah's attribute of being swift to take account and deliver justice. It beseeches the Almighty to shake the ranks of the enemies and defeat them. One of the biggest examples of how the dua against the enemies of Islam was fulfilled was in the battle of Badr when Allah (سُبْحَانَهُ وَتَعَالَى) sent down divine help for Muslims to fight against the enemies who outnumbered Muslims.
Fighting against enemies shouldn't be the first resort but the last. Islam encourages dialogue and the way of peace. However, if the enemy is bent on aggression, then one must give an appropriate response to defend themselves. In such circumstances, the dua against enemies helps bring courage and solace to the righteous. It reminds them that Allah's help is near, and He has power over all outcomes.
Narrated by Abdullah bin Abi' Aufa and reported in Sahih al-Bukhari, 2933, during the battle of Al-Ahzab, Prophet Muhammad (ﷺ) prayed to Allah (سُبْحَانَهُ وَتَعَالَى) with the dua listed below for the defeat of the enemies.
The first and foremost etiquette of reciting any dua is to be humble and sincere in your prayers. When praying against enemies, do not do it in a way that you wish ill upon someone; rather, pray for their guidance and the softening of their hearts so that they are guided towards the right. Ask Allah (سُبْحَانَهُ وَتَعَالَى) to protect you from the harm or plots of the enemies and for your righteousness and strength. Dua made with humility and faith that it is only Allah (سُبْحَانَهُ وَتَعَالَى) who will protect you and guide you is heard as it is the first and basic etiquette that you pray with full faith in Allah (سُبْحَانَهُ وَتَعَالَى).
Joy & Distress Duas
Allaahumma munzilal-kitaabi, saree'al-hisaabi, ihzimil-'ahzaaba, Allaahumma ihzimhum wa zalzilhum.
Allah, Revealer of the Book, Swift to account, defeat the groups (of disbelievers). O Allah, defeat them and shake them.
A meaningful supplication can have significant outcomes that can change a person's life. Dua made against enemies and for one's strength and patience offers an individual insight into navigating through people who do not have the best intentions for them. Dua is an act of worship, and praying in times of adversity strengthens one's belief in their Creator and allows them to trust Him to handle the difficult matters and protect them from the evil that is there.
It prevents people from transgressing or using force or oppression against their enemies and inculcates a resilient and fearless attitude that Allah (سُبْحَانَهُ وَتَعَالَى) will not let any harm come to them. Leaving matters in the hands of Allah (سُبْحَانَهُ وَتَعَالَى) and praying for the guidance of the enemies and a forgiving attitude can save one from sinning or any unlawful acts.
