Sunan Abi Dawud, Hadith 1065 ⓘ
Narrated Zayd ibn Arqam: Ilyas ibn AbuRamlah ash-Shami said: I witnessed Mu'awiyah ibn AbuSufyan asking Zayd ibn Arqam: Did you offer along with the Messenger of Allah the Friday and 'Id prayers synchronised on the same day? He said: Yes. He asked: How did he do? He replied: He offered the 'Id prayer, then granted concession to offer the Friday prayer, and said: If anyone wants to offer it, he may offer.
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا إِسْرَائِيلُ، حَدَّثَنَا عُثْمَانُ بْنُ الْمُغِيرَةِ، عَنْ إِيَاسِ بْنِ أَبِي رَمْلَةَ الشَّامِيِّ، قَالَ شَهِدْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ وَهُوَ يَسْأَلُ زَيْدَ بْنَ أَرْقَمَ قَالَ أَشَهِدْتَ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم عِيدَيْنِ اجْتَمَعَا فِي يَوْمٍ قَالَ نَعَمْ . قَالَ فَكَيْفَ صَنَعَ قَالَ صَلَّى الْعِيدَ ثُمَّ رَخَّصَ فِي الْجُمُعَةِ فَقَالَ " مَنْ شَاءَ أَنْ يُصَلِّيَ فَلْيُصَلِّ " .
