Abu Hassan reported,

I said to Abu Hurairah, "Two of my sons have died. Can you narrate to us a hadith from the Messenger of Allah ﷺ that will console our hearts concerning our dead?"He replied, "Yes. Their little ones are the small swimmers of 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 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."

Sahih

عن أبي حسان، قال

قلت لأبي هريرة: إنه قد مات لي ابنان، فما أنت محدثي عن رسول الله ﷺ بحديث تطيب أنفسنا عن موتانا؟ قال: قال: نعم، صغارهم دعاميص الجنة، يتلقى أحدهم أباه- أو قال: أبويه- فيأخذ بثوبه- أو قال: بيده- كما آخذ أنا بصنفة ثوبك هذا، فلا يتناهى- أو قال: فلا ينتهي- حتى يدخله الله وأباه الجنة.
