All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

Dear questioner, thank you very much for having confidence in us, and we implore Allah to guide the baffled Muslim Ummah to the Right Path, and to redress the balance of power and restore sovereignty to Muslims in the near future, insha’ Allah.

As far as Islamic Shari`ah is concerned, it is permissible to make du`aa’ Al-Qunut in every obligatory Prayer for our brothers and sisters in Gaza. In fact, it is recommended to do so and to think of other practical ways to help stop the current aggression against them. During times of affliction and crises, Muslims, rulers and the ruled, scholars and individuals should lend a helping hand to afflicted or oppressed people. Du`aa’  is a strong weapon that any Muslim should use.

Responding to your question, Dr. Sano Koutoub Moustapha, deputy chairman of the International Fiqh Academy and professor of fiqh and its principles at the International Islamic University, Malaysia, states,

Thank you for your kind question.

It is strongly recommended to recite du`aa’ Al-Qunut in all Prayers for our beloved brothers and sisters in Gaza seeking divine assistance for them, and wishing that Almighty Allah grants mercy to all those who have been killed unjustly and inhumanly. This is firmly in line with the Prophet's (peace and blessings be upon him) practice when the Muslims faced difficult moments and situations such as the situation of people of Gaza. Surely, the people of Gaza badly need our continuous Prayers and du`aa’s for them in all our prostrations. The oppressors and those who help them must be ready for their days which will surely and certainly come. 

Moreover, Sheikh `Abdul-Majeed Subh, a prominent Azharite scholar, adds:

It is permissible for Muslims to offer du`aa’ Al-Qunut in each obligatory Prayer during times of calamity and affliction. We are now facing a great catastrophe and it is therefore good to offer this du`aa’ in the daily Prayers.

Ibn `Abbas (may Allah be pleased with him) is reported to have said that the Messenger of Allah (peace and blessings be upon him) made qunut consecutively for one month in all the five daily Prayers. At the end of each Prayer, after saying "Allah hears him who praises Him" in the last rak`ah, he would supplicate Almighty Allah against Ri`l, Dhakwan, and `Usiyyah of Banu Sulaim, and the people behind him would say Ameen.
