Shaykh Muhammad Nasir al-Din al-Albānī (rahimahullah) mentions that four supplications have been narrated regarding the Qunūt du‘ā:

1. The commonly recited Qunūt du‘ā: 

اللهم اهدنا فيمن هديت، وعافنا فيمن عافيت، وتولنا فيمن توليت، وبارك لنا فيما أعطيت، وقنا شر ما قضيت، فإنك تقضي ولا يقضى عليك، وإنه لا يذلّ من واليتَ، ولا يعزّ من عاديت، تباركت ربنا وتعاليت، لا منجا منك إلا إليك

O Allāh, guide us with those You have guided, heal us with those You have healed, care for us with those You have cared for, bless us in what You have given, and protect us from the evil of what You have decreed. Indeed, You decree while no one decrees against You. Whomever You show loyalty towards will never be humiliated and whoever You show enmity towards will never be honoured. Blessed are You, our Lord, and You are exalted far above (any deficiencies). There is no shelter from You except with You.

2. The Prophet ﷺ would say at the end of his Qunūt du‘ā: 

اللهم إِنَّا نعوذ برضاك من سخطك، وبعفوك من عقوبتك، وبك منك، لاَ نُحْصي ثَنَاءً عليك، أَنت كما أَثنيت على نفسك

“O Allāh, we seek refuge in your good-pleasure from your anger, and in your forgiveness from your punishment and we seek refuge in your mercy from your wrath. We cannot reckon the praise due to you. You are as you have praised yourself.”

3. ‘Umar ibn al-Khaṭṭāb (radiyallahu ‘anhu) included in his Qunūt du‘ā:

اللهم قاتل الكفرة الذين يصدون عن سبيلك، ويكذبون رسلك، ولا يؤمنون بوعدك، وخالف بين كلمتهم، وألق في قلوبهم الرعب، وألق عليهم رجزك وعذابك، إله الحق

O Allāh, curse the disbelievers who obstruct people from Your path and have denied Your Messenger and disbelieve in Your promise. O Allāh, oppose their words, put fear in their hearts and send upon them Your punishment, O Lord of Truth.

Then ‘Umar (radiyallahu ‘anhu) would send salutations upon the Prophet ﷺ, supplicate for goodness for the Muslims and seek forgiveness for them. 

Then he would end by saying:

اللهم إياك نعبد، ولك نصلي ونسجد، وإليك نسعى ونحفد، ونرجو رحمتك ربنا، ونخاف عذابك الجد، إن عذابك لمن عاديت مُلْحَقٌ

O Allāh, You alone we worship, we pray to You, we prostrate for You, we strive for You, we fear Your punishment and we hope in Your mercy. Verily, Your punishment of the disbelievers will be carried out.”

4. In the time of ‘Umar ibn al-Khattab (radiyallahu ‘anhu), the Ṣaḥābī Ubayy ibn Ka‘b (radiyallahu ‘anhu) used to end his Qunūt with sending salutations upon the Prophet ﷺ.

Notes:

• It is allowed for the Imām to add other comprehensive supplications that have been narrated from the Prophet ﷺ, such as asking Allāh for good in this world and the next, asking Allāh for forgiveness of sins and other supplications.^[1]

However, the Qunūt du‘ā should not be lengthy. Early scholars such as al-Baghawi, al-Nawawi^[2] and contemporary scholars such as Shaykh Ibn Baz^[3] and others stated that it is disliked to make the Qunūt dua lengthy. 

Shaykh al-Islām Ibn Taymiyyah (rahimahullah): “The Prophetic supplications are the best supplications. The person who uses them has taken the safest path and guarantees himself the best results. Other supplications that people add from themselves may be forbidden or disliked and some even include shirk!”^[4]

• When the Imam recites the Qunūt in Witr, the one praying behind him should say “Āmīn” after the supplications. Imam Ahmad was asked about the Qunūt in Witr, he said: “Those who pray behind the Imam say “Āmīn” in the places where it should be said.”^[5]

As for when the Imam praises Allāh then he should either remain silent or praise Allāh quietly such as saying “Subhānak”. This is according to many scholars such as Hafidh Nawawi, Lajnah Da’imah (headed by Shaykh Ibn Baz), Shaykh Ibn Uthaymin and others. Some scholars such as Shaykh al-Albani hold that it is better to remain silent rather than praising Allah when the Imam is not making du‘ā.^[6]

The part of the Witr Qunūt that contains dua is:

اللهم اهدني فيمن هديت، وعافني فيمن عافيت، وتولني فيمن توليت، وبارك لي فيما أعطيت، وقني شر ما قضيت

The part that contains praise is:

إنك تقضي ولا يقضى عليك، إنه لا يذل من واليت، ولا يعز من عاديت، تباركت ربنا وتعاليت
