Umm Jundab reported,

I saw the Messenger of Allah ﷺ throw the pebbles at Jamrat al-Aqaba from the bottom of the valley on the Day of Sacrifice. He then turned away, and a woman from Khatham followed him with a young son of hers who was afflicted and could not speak.She said, "Messenger of Allah, this is my son and the only one left of my family, and he is afflicted and cannot speak."The Messenger of Allah ﷺ said, "Bring me some water."Water was brought to him, and he washed his hands and rinsed his mouth, then gave the water to her and said, "Give him some of this to drink, pour some of it over him, and seek healing from Allah for him."The narrator said, "I met the woman and said, 'Would you give me some of it?'"She replied, "It is only for this afflicted child."He said, "I met the woman a year later and asked her about the boy."She said, "He has been cured and possesses an intelligence unlike the intelligence of ordinary people."

حدثنا أبو بكر بن أبي شيبة حدثنا عبد الرحيم بن سليمان عن يزيد بن أبي زياد عن سليمان بن عمرو بن الأحوص

عن أم جندب قالت

رأيت رسول الله ﷺ رمى جمرة العقبة من بطن الوادي يوم النحر ثم انصرف وتبعته امرأة من خثعم ومعها صبي لها به بلاء لا يتكلم فقالت يا رسول الله إن هذا ابني وبقية أهلي وإن به بلاء لا يتكلم فقال رسول الله ﷺ ائتوني بشيء من ماء فأتي بماء فغسل يديه ومضمض فاه ثم أعطاها فقال اسقيه منه وصبي عليه منه واستشفي الله له قالت فلقيت المرأة فقلت لو وهبت لي منه فقالت إنما هو لهذا المبتلى قالت فلقيت المرأة من الحول فسألتها عن الغلام فقالت برأ وعقل عقلا ليس كعقول الناس
