A friend sent me the following. Could you please verify?
1. Ibn ‘Umar (radiyallahu ‘anhuma) said: When the Messenger of Allah (sallallahu ‘alayhi wa sallam) broke his fast, he would say:
ﺫَﻫَﺐَ ﺍﻟﻈَّﻤَﺄُ ﻭَﺍﺑْﺘَﻠَّﺖْ ﺍﻟْﻌُﺮُﻭﻕُ ﻭَﺛَﺒَﺖَ ﺍﻷَﺟْﺮُ ﺇِﻥْ ﺷَﺎﺀَ ﺍﻟﻠَّﻪُ
Dhahabaz-zama-u, wabtallatil-‘uruqu wa thabatal-ajru insha Allah
(Thirst has gone, the veins are moist, and the reward is assured, if Allah wills).”
This is the reliable du’a.
2. Do not recite this famous Du’a while breaking the Fast:
ُاللّهُمَّ لَكَ صُمتُ وَ عَلَي رِزقِكَ أَفطَرت
“Allahumma laka sumtu wa ‘ala rizqika aftartu”
This narration is mentioned in Sunan Abu Dawud, Book of Fasting. The narrator of this narration, Mu’adh ibn Zuhra is weak.
This Du’a is not proven from the Sunnah of Nabi (sallallahu ‘alayhi wasallam), not proven from the Sahih Hadith.
When citing the du’as to be recited at the time of iftar (breaking the fast) ‘Allamah Nawawi (rahimahullah) has cited both of the above du’as.
(Al-Adhkar, Hadith: 575, 576)
The second du’a which is very popular has support from another chain of narration in Tabarani. Your friend has only cited the narration of Abu Dawud. Both these chains strengthen each other.
The latter-day Shafi’i Fiqh and Hadith master; Ibn Hajar Al-Haytami (rahimahullah) said: ‘This is sufficient to rely upon in situations like this.’ (i.e, for the purpose of du’a)
(See Majma’uz Zawaid, vol.3 pg.156 and Futuhatur Rabbaniyyah, vol.4 pg.341)
Therefore, one is allowed to recite both du’as. It is incorrect to stop people from reciting this du’a, as weak Hadiths have been declared suitable for practice in the case of du’as.
(See Mustadrak Hakim, beginning of the Chapter on du’as)
And Allah Ta’ala Knows best.
