What is the dua for breaking the fast?
Short answer: “Dhahaba al-ẓama’u wabtallat al-‘uruqu wa thabata al-ajru in sha’ Allah” – the thirst is gone, the veins are moistened and the reward is confirmed, if Allah wills.
At iftar, say Bismillah and break the fast with fresh dates, or dry dates, or water (Abu Dawud 2356). The Prophet ﷺ would then say: ذَهَبَ الظَّمَأُ وَابْتَلَّتِ الْعُرُوقُ وَثَبَتَ الْأَجْرُ إِنْ شَاءَ اللَّهُ (Abu Dawud 2357). The fasting person’s dua at iftar is not rejected, so ask Allah for what you need. See the dua for breaking the fast and your Ramadan timetable.
