Wiping the child under his chin
وَ عَنِ الصَّادِقِ ع إِذَا شَرِبَ الْمَاءَ يُحَرِّكُ الْإِنَاءَ وَ يُقَالُ يَا مَاءُ مَاءُ زَمْزَمَ وَ مَاءُ الْفُرَاتِ يُقْرِئُكَ السَّلَامَ
And from the Sadiq-asws, when he-asws drank the water, he-asws moved (shook) the utensil, and he-asws said: ‘O water! Water of Zamzam and water of the Euphrates convey the greetings!
وَ مَاءُ زَمْزَمَ شِفَاءٌ مِنْ كُلِّ دَاءٍ وَ هُوَ دَوَاءٌ مِمَّا شُرِبَ لَهُ وَ مَاءُ الْمِيزَابِ يَشْفِي الْمَرِيضَ وَ مَاءُ السَّمَاءِ يَدْفَعُ الْأَسْقَامَ وَ نُهِيَ عَنِ الْبَرَدِ لِقَوْلِهِ تَعَالَى يُصِيبُ بِهِ مَنْ يَشاءُ وَ مَاءُ الْفُرَاتِ يُصَبُّ فِيهِ مِيزَابَانِ مِنَ الْجَنَّةِ وَ تَحْنِيكُ الْوَلَدِ بِهِ يجبه [يُحَبِّبُهُ] إِلَى الْوَلَايَةِ.
And water of Zamzam is a healing from every illness, and it is a cure from whatever it is drunk for, and water of the spout (of the Kaaba) is a healing for the patient, and water of the sky repels the illness, and he-asws forbade from the cold due to Words of the Exalted: So He Hits the ones He so Desires to [24:43], and the water of Euphrates, two spouts from the Paradise pour into it, and wiping the child under his chin with it pulls him to the Wilayah’.[1]
