Ali sent a piece of gold still embedded in its ore from Yemen to the Messenger of Allah ﷺ, and the Messenger of Allah ﷺ divided it among four men. The hadith continues that the Messenger of Allah ﷺ said, "From the offspring of this man will come a people who recite the Quran, but it will not pass beyond their throats. They will kill the people of Islam and spare the worshippers of idols. They will pass out of Islam as an arrow passes through its target. If I live to see them, I will surely kill them as the people of Aad were killed."
بعث علي وهو باليمن بذهبة في تربتها إلى رسول الله ﷺ فقسمها رسول الله ﷺ بين أربعة نفر… وفيه: فقال رسول الله ﷺ: إن من ضئضئ هذا قوما يقرأون القرآن لا يجاوز حناجرهم يقتلون أهل الإسلام، ويدعون أهل الأوثان، يمرقون من الإسلام كما يمرق السهم من الرمية، لئن أدركتهم لأقتلنهم قتل عاد.
