عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ وَقَفَ بِعَرَفَةَ وَهُوَ مُرْدِفٌ أُسَامَةَ بْنَ زَيْدٍ فَقَالَ: ((هَذَا الْمَوْقِفُ وَكُلُّ عَرَفَةَ مَوْقِفٌ))
It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) stood at Arafah, and at that time Sayyiduna Usamah bin Zaid (may Allah be pleased with him) was riding behind him on his mount. The Prophet (peace and blessings be upon him) said: "This is the place of standing, and all of Arafah is a place for standing."
