حَدَّثَنَا قَبِيصَةُ ، حَدَّثَنَا سُفْيَانُ ، عَنْ مُعَاوِيَةَ ، بِهَذَا. وَعَنْ حَبِيبِ بْنِ أَبِي عَمْرَةَ ، عَنْ عَائِشَةَ بِنْتِ طَلْحَةَ ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، عَنِ النَّبِيِّ صلى الله عليه وسلم سَأَلَهُ نِسَاؤُهُ عَنِ الْجِهَادِ فَقَالَ " نِعْمَ الْجِهَادُ الْحَجُّ " .
the mother of the faithful believers: The Prophet (ﷺ) was asked by his wives about the Jihad and he replied, "The best Jihad (for you) is (the performance of) Hajj."
