It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that he said: The Prophet (peace and blessings be upon him) came to Sayyidah Aishah (may Allah be pleased with her), and with her was a woman who had her child with her, whose nostrils were flowing with blood. The Prophet (peace and blessings be upon him) asked: "What is the matter with him?" The people said that he had udhrah (swelling of the throat). He (peace and blessings be upon him) said: "Woe to you! Do not kill your children. Any woman whose child suffers from udhrah should take Indian costus, rub it in water, and then give it to him as snuff through the nose." Then he (peace and blessings be upon him) ordered Sayyidah Aishah (may Allah be pleased with her), so she did that with the child, and he recovered. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
