Sayyiduna Sa’d bin Mu’adh (may Allah be pleased with him) says that I said to Umayyah bin Khalaf that I heard Muhammad (peace and blessings of Allah be upon him) say that they will kill you. Umayyah said,“Me?”Sayyiduna Sa’d (may Allah be pleased with him) said,“Yes.”Umayyah said,“By Allah! Muhammad’s (peace be upon him) word is never false.”So Allah Almighty had him killed on the day of Badr. There is also an incident in this hadith, but the main content of the hadith is this.
