Sulayman Taymi reported,

Suwayd bin Saeed and Muhammad bin Abdul-Ala reported to us, their wording being nearly identical, saying, Mutamir reported to us from his father, from Abu Saleel, from Abu Hassan, who said:I said to Abu Hurairah, "Two of my sons have died. Can you tell me something from the Messenger of Allah ﷺ that would comfort our hearts concerning our dead?"Abu Hurairah replied, "Yes. He said, 'Their little ones are the little ones who dart freely about Paradise. One of them meets his father,' or he said, 'his parents, and takes hold of his garment,' or he said, 'his hand, just as I am now holding the hem of this garment of yours, and he does not let go,' or he said, 'he does not stop until Allah admits him and his father into Paradise.'"In Suwayd's version he said, Abu Saleel reported to us, and he said, "Have you heard anything from the Messenger of Allah ﷺ that would comfort our hearts concerning our dead?" He replied, "Yes."
