the Messenger of Allah said: “Al-Yawmul-Maw’ud (the Promised Day) is the Day of Resurrection, and Al-Yawmul-Mashhud (the Attended Day) is the Day of Arafah, and Ash-Shahid (the witness) is Friday.” He said: “The sun does not rise nor set, upon a day that is more virtuous than it. In it, there is an hour in which no believing worshipper makes a supplication to Allah for good, except that Allah answers it for him, and he does not seek Allah’s aid for something, except that He aids him in it.”
رَسُولُ اللَّهِ ﷺ الْيَوْمُ الْمَوْعُودُ يَوْمُ الْقِيَامَةِ وَالْيَوْمُ الْمَشْهُودُ يَوْمُ عَرَفَةَ وَالشَّاهِدُ يَوْمُ الْجُمُعَةِ وَمَا طَلَعَتِ الشَّمْسُ وَلاَ غَرَبَتْ عَلَى يَوْمٍ أَفْضَلَ مِنْهُ فِيهِ سَاعَةٌ لاَ يُوَافِقُهَا عَبْدٌ مُؤْمِنٌ يَدْعُو اللَّهَ بِخَيْرٍ إِلاَّ اسْتَجَابَ اللَّهُ لَهُ وَلاَ يَسْتَعِيذُ مِنْ شَرٍّ إِلاَّ أَعَاذَهُ اللَّهُ مِنْهُ
