أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى ، عَنْ إِسْرَائِيلَ ، عَنْ عُثْمَانَ بْنِ الْمُغِيرَةِ ، عَنْ إِيَاسِ بْنِ أَبِي رَمْلَةَ ، قَالَ : شَهِدْتُ مُعَاوِيَةَ يَسْأَلُ زَيْدَ بْنَ أَرْقَمَ : أَشَهِدْتَ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِيدَيْنِ اجْتَمَعَا فِي يَوْمٍ؟ قَالَ : نَعَمْ.
قَالَ : فَكَيْفَ صَنَعَ؟ قَالَ : صَلَّى الْعِيدَ، ثُمَّ رَخَّصَ فِي الْجُمُعَةِ، فَقَالَ :" مَنْ شَاءَ أَنْ يُصَلِّيَ، فَلْيُصَلِّ "
