Two of my sons died, so I said to Abu Hurairah, "Have you heard anything from the Messenger of Allah ﷺ that you can tell us to comfort our hearts concerning our deceased?"He replied, "Yes. Their little ones are the small ones of Paradise. One of them will meet his father," or he said, "his parents, and will take hold of the edge of his garment," or "his hand, just as I am taking hold of the hem of this garment of yours, and he will not let go until Allah admits him and his father into Paradise."
حدثنا محمد بن أبي عدي عن سليمان عن أبي السليل
توفي ابنان لي فقلت لأبي هريرة سمعت من رسول الله ﷺ حديثا تحدثناه يطيب بأنفسنا عن موتانا قال نعم صغارهم دعاميص الجنة يلقى أحدهم أباه أو قال أبويه فيأخذ بناحية ثوبه أو يده كما آخذ بصنفة ثوبك هذا فلا يفارقه حتى يدخله الله وأباه الجنة
