Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The believer dies with sweat on the forehead."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and in al-Mu'jam al-Kabir within a long hadith. Its narrators are thiqat (trustworthy) and are the narrators of the Sahih.
