Sayyiduna Ammar bin Yasir (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The example of my Ummah is like that of rain: it is not known whether its first part is better or its last part."
Ahmad, al-Bazzar and al-Tabarani recorded it. The narrators of al-Bazzar are the narrators of the Sahih, except al-Hasan bin Qaza'ah and Ubayd bin Sulayman al-Agharr, and both of them are thiqat (trustworthy); there is a difference of opinion about Ubayd that does no harm.
