Is there an authentic Dua for Iftar narrated from the Prophet ﷺ?

Yes, there are at least two authentic Duas for Iftar narrated from the Prophet ﷺ.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا هُشَيْمٌ، عَنْ حُصَيْنٍ، عَنْ مُعَاذِ بْنِ زُهْرَةَ، أَنَّهُ بَلَغَهُ ” أَنَّ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَفْطَرَ قَالَ: اللَّهُمَّ لَكَ صُمْتُ، وَعَلَى رِزْقِكَ أَفْطَرْتُ

 Mu’adh ibn Zuhrah said that it has reached him that, upon ending his fast the Prophet ﷺ used to say: ‘O Allah, I have fasted for you, and with your provision (Rizq) I have ended my fast.’ (Abu Dawood, 2358).

The Hadith above mentions a Dua for Iftar from the Prophet ﷺ. However, the narration is Mursal (missing the Sahabi from the chain). The scholars differed over the Mursal Hadith, some considered it to be weak, whilst others accepted it if the rest of the chain was sound. The Hanafi scholars tended to incline towards this second opinion.

عَن معَاذ: ” كَانَ رَسُول الله صَلَّى اللَّهُ عَلَيْهِ وَسَلَّم َ إِذا أفطر قَالَ: اللَّهُمَّ لَك صمت وَعَلَى رزقك أفطرت “. هَذَا الحَدِيث رَوَاهُ أَبُو دَاوُد فِي «سنَنه» بِهَذَا اللَّفْظ عَن مُسَدّد، نَا هشيم، عَن حُصَيْن، عَن معَاذ بن زهرَة أَنه بلغه ” أَن النَّبِي صَلَّى اللَّهُ عَلَيْهِ وَسَلَّم َ كَانَ إِذا أفطر قَالَ … ” (فَذكره) وَهَذَا إِسْنَاد حسن لكنه مُرْسل؛ معَاذ بن زهرَة لم يدْرك النَّبِي صَلَّى اللَّهُ عَلَيْهِ وَسَلَّم. (البدر المنير في تخريج الأحاديث والأثار الواقعة في الشرح الكبير)

Upon ending his fast the Messenger of Allah ﷺ used to say: ‘O Allah, I have fasted for you, and with your provision (Rizq) I have ended my fast.’ This Hadith has been narrated by Abu Dawood in his Sunnan, with this wording from Musaddad, from Hushaym, from Husayn from Mu’adh ibn Zuhrah said that it has reached him that, upon ending his fast the Prophet ﷺ used to say, then he mentioned it (the Hadith). This chain is Hasan but Mursal. Mu’adh ibn Zuhrah did not meet the Prophet ﷺ. (Imam Siraj al-Deen Ibn al-Mulaqqin, al-Badr al-Muneer).

Similar statements have been made in many other classical works too, see (Asnaa al-Matalib, Nihayatu al-Muhtaaj, Sharh al-Mahali ala al-Minhaaj). So, the chain itself is Hasan. Therefore, many scholars will consider this to be an authentic Hadith. Since being Mursal is not usually a defect according to them.

قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، إِذَا أَفْطَرَ قَالَ: ذَهَبَ الظَّمَأُ وَابْتَلَّتِ الْعُرُوقُ، وَثَبَتَ الْأَجْرُ إِنْ شَاءَ اللَّهُ

He (Ibn Umar, May Allah Most High be pleased with him) said that upon ending his fast the Messenger of Allah ﷺ used to say, ‘Thirst has gone, the vessels have been moistened, and reward is established, if Allah wills.’ (Abu Dawood, 2357).

The Hadith above has a different Dua for Iftar. It is not uncommon for there to be a number of supplications for the same thing. In such a case one can select and vary the supplication one makes. The Hadith itself is Hasan and therefore authentic.

«إِذَا أَفْطَرَ ذَهَبَ الظَّمَأُ وَابْتَلَّتِ الْعُرُوقُ وَثَبَتَ الْأَجْرُ إِنْ شَاءَ اللَّهُ – تَعَالَى -». رَوَاهُ أَبُو دَاوُدَ، وَالدَّارَقُطْنِيُّ، وَحَسَّنَ إِسْنَادَهُ. (المبدع في شرح المقنع)

‘Thirst has gone, the vessels have been moistened, and reward is established, if Allah wills.’ Narrated by Abu Dawood and al-Darqutni, and he considered the chain to be Hasan. (Imam Burhan al-Deen Ibn al-Muflih).

And Allah Most High Knows Best.
