Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Darda (may Allah be pleased with him) that he said: I submitted, "O Messenger of Allah (peace and blessings be upon him)! The wealthy have taken all the reward. Just as we pray, they also pray; just as we fast, they also fast; and just as we perform Hajj, they also perform Hajj. And they also give charity, whereas we do not find anything to give in charity." The narrator says: The Prophet (peace and blessings be upon him) said, "Shall I not tell you something, that when you do it, you will catch up with those who have surpassed you, and those who come after you will not be able to catch up with you except by doing what you do? After every prayer, recite Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times."
