It was narrated from Ibn 'Abbas that:

a woman helf up a child of hers to the Messenger of Allah and said: "O Messenger of Allah, is there Hajj for this one?" He said: "Yes, and you will be rewarded. "

أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ مُحَمَّدِ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ امْرَأَةً، رَفَعَتْ صَبِيًّا لَهَا إِلَى رَسُولِ اللَّهِ ﷺ قَالَتْ يَا رَسُولَ اللَّهِ أَلِهَذَا حَجٌّ قَالَ " نَعَمْ وَلَكِ أَجْرٌ " .
