Validity of a child's hajj, and the reward of the one who takes him for Hajj
Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، وَابْنُ أَبِي عُمَرَ، جَمِيعًا عَنِ ابْنِ، عُيَيْنَةَ - قَالَ أَبُو بَكْرٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، - عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، مَوْلَى ابْنِ عَبَّاسٍ عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم لَقِيَ رَكْبًا بِالرَّوْحَاءِ فَقَالَ " مَنِ الْقَوْمُ " . قَالُوا الْمُسْلِمُونَ . فَقَالُوا مَنْ أَنْتَ قَالَ " رَسُولُ اللَّهِ " . فَرَفَعَتْ إِلَيْهِ امْرَأَةٌ صَبِيًّا فَقَالَتْ أَلِهَذَا حَجٌّ قَالَ " نَعَمْ وَلَكِ أَجْرٌ " .
Ibn Abbas reported that Allah's Apostle (ﷺ) met some riders at al-Rauha and asked who they were. They replied that they were Muslims. They said: Who art thou? He said: (I am) Messengef of Allah. A woman (then) lifted up a boy to him and said: Would this child be credited with having performed the Hajj? Thereupon he said: Yes, and you will have a reward.
