“I heard Salim bin ‘Abdullah narrating from his father that the Messenger of Allah ﷺ said: ‘You should eat this black seed, for in it there is healing from every disease, except the Sam (death).’” (Using translation from Ibn Mājah 3448)
عَنْ رَسُولِ اللهِ ﷺ قَالَ «عَلَيْكُمْ بِالْحَبَّةِ السَّوْدَاءِ فَإِنَّ فِيهَا شِفَاءً مِنْ كُلِّ دَاءٍ إِلَّا السَّامَ وَالسَّامُ الْمَوْتُ»
