Hajj is the Jihad of women
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ حَبِيبِ بْنِ أَبِي عَمْرَةَ، عَنْ عَائِشَةَ بِنْتِ طَلْحَةَ، عَنْ عَائِشَةَ، قَالَتْ قُلْتُ يَا رَسُولَ اللَّهِ عَلَى النِّسَاءِ جِهَادٌ قَالَ " نَعَمْ عَلَيْهِنَّ جِهَادٌ لاَ قِتَالَ فِيهِ الْحَجُّ وَالْعُمْرَةُ " .
It was narrated that ‘Aishah said: “I said: ‘O Messenger of Allah, is Jihad obligatory for women?’ He said: “Yes: Upon them is a Jihad in which there is no fighting: Al-Hajj and Al-‘Umrah.”
