Muwatta Malik, Book 20, Hadith 253 (USC-MSA) ⓘ

Yahya related to me from Malik from Ibrahim ibn Uqba from Kurayb the mawla of Abdullah ibn Abbas from Ibn Abbas that the Messenger of Allah, may Allah bless him and grant him peace, passed a woman in a litter and it was said to her, "This is the Messenger of Allah, may Allah bless him and grant him peace," and she took the forearms of a young boy who was with her and said, "Does this one have a hajj, Messenger of Allah?" and he said, "Yes, and you have a reward."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، مَوْلَى عَبْدِ اللَّهِ بْنِ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم مَرَّ بِامْرَأَةٍ وَهِيَ فِي مِحَفَّتِهَا فَقِيلَ لَهَا هَذَا رَسُولُ اللَّهِ صلى الله عليه وسلم فَأَخَذَتْ بِضَبْعَىْ صَبِيٍّ كَانَ مَعَهَا فَقَالَتْ أَلِهَذَا حَجٌّ يَا رَسُولَ اللَّهِ قَالَ ‏ "‏ نَعَمْ وَلَكِ أَجْرٌ ‏" ‏ ‏.‏
