Al-Qasim b. Ahmad b. Ja’far narrated from al-Qasim b. Muhammad from Abu Ja’far from Muhammad b. Ya’la Abu ‘Amr from Dharih, who said: I said to Abu ‘Abd Allah, peace be upon him. "I suffer from rumbling (al-qaraqir) and pain in my belly.” He replied: “What prevents you from [taking] black cumin? It is a cure for every illness except the poison.”
From Abu Ja’far al-Baqir, peace be upon him, who said: ‘The Messenger of Allah, blessings of Allah on him and his family, said concerning this black cumin that in it is a cure for every illness except the poison. It was said: “O Messenger of Allah, what is the poison?” He replied: “Death.”’
From Zarara b. A’yan, who said: I heard Abu Ja’far al-Baqir, peace be upon him, when asked about the statement of the Messenger of Allah, blessings of Allah on him and his family, about black cumin, say: ‘Yes, the Messenger of Allah said that and made an exception in it, for he said: “except the poison”. But shall I show you what is more effective than it, and about which the Prophet, blessings on him and his family, has not made an exception?’ I said: ‘Yes indeed, O son of the Messenger of Allah.’ He said: ‘Prayer repels destiny (al-qada’) and that has been decided conclusively, and alms extinguish anger,’ and he brought his fingers together.
