Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Umamah (may Allah be pleased with him) says: A man asked, "O Messenger of Allah! Was Adam (peace be upon him) a prophet?" He (peace and blessings be upon him) replied, "Yes, he was taught and he was spoken to (by Allah, the Exalted)." He asked, "What was the time span between him and Nuh (peace be upon him)?" He (peace and blessings be upon him) replied, "Ten centuries (or ten generations)." He asked, "What was the time span between Nuh (peace be upon him) and Ibrahim (peace be upon him)?" He (peace and blessings be upon him) replied, "Ten centuries." Then the companions asked, "O Messenger of Allah! How many messengers have passed in total?" He (peace and blessings be upon him) replied, "Three hundred and fifteen, a large group."
