Silsilat al-Ahadith al-Sahihah

Muhammad bin Ziyad Al-Hani says: When the people who possess the ruling of martyrdom were mentioned in the presence of Abu ‘Unbah Khawlani, those present mentioned people who died from abdominal illness, those who died from plague, and women who died during childbirth. But Abu ‘Unbah became angry and said: The noble Companions (may Allah be pleased with them) narrated to us from the Prophet (peace and blessings of Allah be upon him) that he said: “The trustworthy people among the creation of Allah are the witnesses of Allah on earth, whether they are martyrs or those who die a natural death.”
