Sayyiduna Imran (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Whoever forgets to offer a prayer should offer it when he remembers it."
Al-Tabarani recorded it in al-Kabir; its chain contains a narrator, Muhammad bin Musa bin Abi Nu'aym, whom Yahya bin Ma'in declared da'if (weak), while Abu Hatim and Ibn Hibban declared him thiqah (trustworthy). Ahmad bin Sinan said: Ibn Abi Nu'aym is thiqah (trustworthy) and saduq (truthful).
