Jabir b. Samura reported: I prayed along with Allah's Messenger (ﷺ) the first prayer. He then went to his family and I also went along with him when he met some children (on the way). He began to pat the cheeks of each one of them. He also patted my cheek and I experienced a coolness or a fragrance of his hand as if it had been brought out from the scent bag of a perfumer.
