Oneness, Uniqueness of Allah (Tawheed)

Bukhari :: Book 9 :: Volume 93 :: Hadith 624

Narrated Ibn 'Umar:

Allah's Apostle said, "Your stay (in this world) in comparison to the stay of the nations preceding you, is like the period between 'Asr prayer and the sun set (in comparison to a whole day). The people of the Torah were given the Torah and they acted on it till midday and then they were unable to carry on. And they were given (a reward equal to) one Qirat each. Then the people of the Gospel were given the Gospel and they acted on it till 'Asr Prayer and then they were unable to carry on, so they were given la reward equal to) one Qirat each. Then you were given the Qur'an and you acted on it till sunset, therefore you were given (a reward equal to) two Qirats each. On that, the people of the Scriptures said, 'These people (Muslims) did less work than we but they took a bigger reward.' Allah said (to them). 'Have I done any oppression to you as regards your rights?' They said, "No." Then Allah said, 'That is My Blessing which I grant to whomsoever I will.' "
