It was narrated that ‘Uthman bin ‘Abdul-Malik said:
“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).’”

حَدَّثَنَا أَبُو سَلَمَةَ، يَحْيَى بْنُ خَلَفٍ حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ عُثْمَانَ بْنِ عَبْدِ الْمَلِكِ، قَالَ سَمِعْتُ سَالِمَ بْنَ عَبْدِ اللَّهِ، يُحَدِّثُ عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " عَلَيْكُمْ بِهَذِهِ الْحَبَّةِ السَّوْدَاءِ فَإِنَّ فِيهَا شِفَاءً مِنْ كُلِّ دَاءٍ إِلاَّ السَّامَ " .
