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, did umra three times:

in the year of Hudaybiya, in the year of al-Qadiyya, and in the year of al-Jiirrana.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم اعْتَمَرَ ثَلاَثًا عَامَ الْحُدَيْبِيَةِ وَعَامَ الْقَضِيَّةِ وَعَامَ الْجِعِرَّانَةِ ‏.‏
