Validity of a child's hajj, and the reward of the one who takes him for Hajj
Sahih Muslim
وَحَدَّثَنِي مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، أَنَّ امْرَأَةً، رَفَعَتْ صَبِيًّا فَقَالَتْ يَا رَسُولَ اللَّهِ أَلِهَذَا حَجٌّ قَالَ " نَعَمْ وَلَكِ أَجْرٌ " .
Karaib reported: A woman lifted a child and said: Messenger of Allah, would he be credited with Hajj? He said: Yes. and for you there would be a reward.
