Hadith on Fasting: The supplication of a person breaking their fast is never turned away

Abdullah ibn Amr ibn Al-‘As reported: The Messenger of Allah, peace be upon him, said, “Indeed, the supplication of the fasting person when he breaks his fast is not turned away.” Ibn Abu Mulaikah said: I heard Abdullah ibn Amr say upon breaking his fast, “O Allah, I ask You by Your mercy, which encompasses all things, that You forgive me.”

عَبْدَ اللَّهِ بْنَ عَمْرِو بْنِ الْعَاصِ يَقُولُ  قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ لِلصَّائِمِ عِنْدَ فِطْرِهِ لَدَعْوَةً مَا تُرَدُّ قَالَ ابْنُ أَبِي مُلَيْكَةَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَمْرٍو يَقُولُ إِذَا أَفْطَرَ اللَّهُمَّ إِنِّي أَسْأَلُكَ بِرَحْمَتِكَ الَّتِي وَسِعَتْ كُلَّ شَيْءٍ أَنْ تَغْفِرَ لِي
