We went out and Ghalib bin Abjar was accompanying us. He fell ill on the way and when we arrived at Medina he was still sick. Ibn Abi 'Atiq came to visit him and said to us, "Treat him with black cumin. Take five or seven seeds and crush them (mix the powder with oil) and drop the resulting mixture into both nostrils, for ʿAisha has narrated to me that she heard the Prophet ﷺ saying, 'This black cumin is healing for all diseases except As-Sam.' Aisha said, 'What is As-Sam?' He said, 'Death."  

لَنَا عَلَيْكُمْ بِهَذِهِ الْحُبَيْبَةِ السَّوْدَاءِ فَخُذُوا مِنْهَا خَمْسًا أَوْ سَبْعًا فَاسْحَقُوهَا ثُمَّ اقْطُرُوهَا فِي أَنْفِهِ بِقَطَرَاتِ زَيْتٍ فِي هَذَا الْجَانِبِ وَفِي هَذَا الْجَانِبِ فَإِنَّ عَائِشَةَ حَدَّثَتْنِي أَنَّهَا سَمِعَتِ النَّبِيَّ ﷺ يَقُولُ إِنَّ هَذِهِ الْحَبَّةَ السَّوْدَاءَ شِفَاءٌ مِنْ كُلِّ دَاءٍ إِلاَّ مِنَ السَّامِ قُلْتُ وَمَا السَّامُ قَالَ الْمَوْتُ  

I heard Messenger of Allah ﷺ saying, "There is healing in black cumin for all diseases except death."  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ فِي الْحَبَّةِ السَّوْدَاءِ شِفَاءٌ مِنْ كُلِّ دَاءٍ إِلاَّ السَّامَ قَالَ ابْنُ شِهَابٍ وَالسَّامُ الْمَوْتُ وَالْحَبَّةُ السَّوْدَاءُ الشُّونِيزُ
