Hadith 17888
It is narrated from Hazrat Abu Saeed bin Abi Fadala (may Allah be pleased with him), who was a companion, that I heard the Prophet (peace and blessings of Allah be upon him) say: When Allah, the Exalted, will gather the first and the last on the Day in which there is no doubt, a caller will announce: Whoever associated anyone with Allah in any deed, let him seek his reward from him, for Allah is most free from all partners in shirk.
