كتاب الحج

Hajj

Yahya related to me from Malik that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, 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."

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 ‏"‏ ‏.‏
