Hajj performed by children

It was narrated that Jabir bin ‘Abdullah said:
“A woman held up a child of hers to the Prophet ﷺ during Hajj and said: ‘O Messenger of Allah, is there Hajj for this one?’ He said: ‘Yes, and you will be rewarded.’”

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَمُحَمَّدُ بْنُ طَرِيفٍ، قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، حَدَّثَنِي مُحَمَّدُ بْنُ سُوقَةَ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ رَفَعَتِ امْرَأَةٌ صَبِيًّا لَهَا إِلَى النَّبِيِّ ﷺ فِي حَجَّتِهِ فَقَالَتْ يَا رَسُولَ اللَّهِ أَلِهَذَا حَجٌّ قَالَ " نَعَمْ وَلَكِ أَجْرٌ " .
