Muwatta Malik, Book 20, Hadith 735 (In-Book)

Yahya related to me from Malik that he had heard that the Messenger of Allah, may Allah bless him and grant him peace, once entered ihram at al-Jiirrana (near Makka) for an umra.

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَهَلَّ مِنَ الْجِعِرَّانَةِ بِعُمْرَةٍ ‏.‏
