عَنْ أَبِي بَكْرٍ بْنِ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ عَنِ امْرَأَةٍ مِنْ بَنِي أَسَدِ بْنِ خُزَيْمَةَ يُقَالُ لَهَا أُمُّ مَعْقِلٍ قَالَتْ: أَرَدْتُ الْحَجَّ فَضَلَّ بَعِيرِي، فَسَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ: ((اعْتَمِرِي فِي شَهْرِ رَمَضَانَ، فَإِنَّ عُمْرَةً فِي شَهْرِ رَمَضَانَ تَعْدِلُ حَجَّةً))
A woman from Banu Asad bin Khuzaymah, Sayyida Umm Ma'qil (may Allah be pleased with her), narrates: I intended to perform Hajj, but my camel was lost. When I asked the Messenger of Allah (peace and blessings be upon him) about it, he said: Perform ‘Umrah in the month of Ramadan, for performing ‘Umrah in this month is equal to Hajj.
