It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that a woman came to the service of the Prophet (peace and blessings of Allah be upon him) with a child and said, "Pray for him (that he may live); I have already buried three children." So the Prophet (peace and blessings of Allah be upon him) said: "You have built a very strong fence to protect yourself from Hell."
