Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) states: I heard the Prophet (peace and blessings be upon him) say: "Whenever Allah Almighty sent a prophet to a people and then caused that prophet to pass away, after him there remained a period in which no prophet was sent, and Allah Almighty will fill Hell with the people of that intervening period."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and its narrators are the narrators of the Sahih except Sadaqah bin Sabiq, and he is thiqah (trustworthy).
