*Du‘a’ Before Iftar is never rejected:*

The Messenger of Allah ﷺ said: “Indeed, the fasting person has a supplication at the time of his Iftār which is not rejected.” (Ibn Mājah 1825)

Ibn Abī Mulaykah (raḥimahullāh) said: I heard ʿAbdullāh b. ʿAmr say upon opening his fast,

اللَّهُمَّ إِنِّي أَسْأَلُكَ بِرَحْمَتِكَ الَّتِي وَسِعَتْ كُلَّ شَىْءٍ أَنْ تَغْفِرَ لِي

O Allah, I beg You – through Your mercy which encompasses everything – to forgive me. (Ibn Mājah 1825)
