It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Treat dhat al-janb (pleurisy) with sea costus (qust bahri) and olive oil." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said, when the people said, "We fear that the Messenger of Allah (peace and blessings be upon him) has dhat al-janb (pleurisy)": "It is (an effect) from Satan, and Allah will not give it power over me." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it; and the opposite of this report has also been narrated from Sayyidah Aishah (may Allah be pleased with her) with a weak chain.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: The Messenger of Allah (peace and blessings be upon him) passed away due to dhat al-janb (pleurisy).
