Yahya related to me from Malik that he had heard that the Messenger of Allah ﷺ said once at Mina, "This place (where I have just sacrificed), and the whole of Mina, is a place of sacrifice," and he said once during umra, "This place of sacrifice" meaning Marwa, "and all the pathways of Makka and its roads are a place of sacrifice."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ بِمِنًى هَذَا الْمَنْحَرُ وَكُلُّ مِنًى مَنْحَرٌ وَقَالَ فِي الْعُمْرَةِ هَذَا الْمَنْحَرُ يَعْنِي الْمَرْوَةَ وَكُلُّ فِجَاجِ مَكَّةَ وَطُرُقِهَا مَنْحَرٌ
