حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ بِمِنًى ‏"‏ هَذَا الْمَنْحَرُ وَكُلُّ مِنًى مَنْحَرٌ ‏"‏ ‏.‏ وَقَالَ فِي الْعُمْرَةِ ‏"‏ هَذَا الْمَنْحَرُ - يَعْنِي الْمَرْوَةَ - وَكُلُّ فِجَاجِ مَكَّةَ وَطُرُقِهَا مَنْحَرٌ ‏"‏ ‏.‏

Yahya related to me from Malik that he had heard that theMessenger of Allah, may Allah bless him and grant him peace, said onceat Mina, "This place (where I have just sacrificed), and the whole ofMina, is a place of sacrifice," and he said once during umra, "Thisplace of sacrifice" meaning Marwa, "and all the pathways of Makka andits roads are a place of sacrifice."
