Hadith on Romans: Muslims rejoice at victory of Christians over idolaters

Abu Sa’id reported: On the day of the battle of Badr, the Romans were victorious over the Persians and the believers were pleased by that. Allah had revealed, “The Romans were defeated in the nearest land, but they will be victorious after their defeat in a few years. To Allah belongs the matter before and after, and on that day the believers will rejoice,” (30:1-4). Thus, the believers rejoiced at the victory of the Romans over the Persians.

عَنْ أَبِي سَعِيدٍ قَالَ لَمَّا كَانَ يَوْمُ بَدْرٍ ظَهَرَتْ الرُّومُ عَلَى فَارِسَ فَأَعْجَبَ ذَلِكَ الْمُؤْمِنِينَ فَنَزَلَتْ غُلِبَتِ الرُّومُ فِي أَدْنَى الْأَرْضِ وَهُم مِّن بَعْدِ غَلَبِهِمْ سَيَغْلِبُونَ فِي بِضْعِ سِنِينَ لِلَّهِ الْأَمْرُ مِن قَبْلُ وَمِن بَعْدُ وَيَوْمَئِذٍ يَفْرَحُ الْمُؤْمِنُونَ قَالَ فَفَرِحَ الْمُؤْمِنُونَ بِظُهُورِ الرُّومِ عَلَى فَارِسَ
