It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that a woman came to the Prophet (peace and blessings be upon him), and with her was a sick son of hers. She said: "O Messenger of Allah! Pray to Allah Almighty to grant this son of mine health and cure." He (peace and blessings be upon him) asked: "Has any child of yours died (in childhood) who will be a forerunner (for you in the Hereafter)?" She said: Yes, they died in the state of Islam. He (peace and blessings be upon him) said: "Then he is a strong shield (for you against Hell), a strong shield."
This chain is hasan (good), because although Abu Ubaydah has been criticised, this same report is narrated with a sahih chain through Abu Zur'ah from Sayyiduna Abu Hurayrah (may Allah be pleased with him).
