The Jews said to ʿUmar. You recite a verse which, is it had been revealed among us, we would have taken that day as a festiva!. ʻUmar said: I know where it was revealed, on what day it was revealed and where the Messenger of Allah ﷺ was when it was revealed. It was revealed on the day of ʿArafah, when the Messenger of Allah ﷺ was standing in ʿArafah, Sufyan said: I am not sure whether it was a Friday or not, i.e., ʿThis day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion.” (al-Ma’idah 5:3).
شِهَابٍأَنَّ الْيَهُودَ قَالُوا لِعُمَرَ إِنَّكُمْ تَقْرَءُونَ آيَةً لَوْ أُنْزِلَتْ فِينَا لاتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا فَقَالَ إِنِّي لَأَعْلَمُ حَيْثُ أُنْزِلَتْ وَأَيَّ يَوْمٍ أُنْزِلَتْ وَأَيْنَ رَسُولُاللهِ ﷺ حِينَ أُنْزِلَتْ؛ أُنْزِلَتْ يَوْمَ عَرَفَةَ وَرَسُولُ اللهِ ﷺ وَاقِفٌ بِعَرَفَةَ قَالَ سُفْيَانُ وَأَشُكُّ يَوْمَ جُمُعَةٍ أَوْ لَا يَعْنِي {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا} [المائدة 3]
