Sayyiduna Abu Nujayd (may Allah be pleased with him), a Companion of the Messenger of Allah (peace and blessings be upon him), narrates: "I heard the Prophet (peace and blessings be upon him) say: 'My Ummah is like the rain; it is not known whether its first part is better or its last.'"
Imam al-Tabarani (may Allah have mercy on him) said: "Abu Nujayd is Sayyiduna Imran bin Husayn al-Khuza'i (may Allah be pleased with him). This hadith is narrated from Imran bin Husayn (may Allah be pleased with him) only with this chain, and Ibn Abi al-Sari is alone in narrating it."
