Al-Mu'jam al-Saghir

Sayyiduna Abu Hurairah (may Allah be pleased with him) says: The poor Muslims came to the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! The wealthy have taken all the reward from us; they pray as we pray, they fast as we fast, and they perform Hajj as we do. But they have wealth, so they give charity from it, and we do not give charity because we do not have wealth. The Prophet (peace and blessings be upon him) said: "Shall I not tell you of an action, that if you do it, you will catch up with those who have gone ahead, and those who come after will not be able to catch up with you, except those who do as you do? After every prayer, say Subhan Allah thirty-three times, Alhamdulillah thirty-three times, and Allahu Akbar thirty-four times." When this hadith reached the wealthy, they also began to recite this remembrance, and did as the poor did. So the poor came again and informed the Prophet (peace and blessings be upon him) of this. The Prophet (peace and blessings be upon him) said: "That is the grace of Allah; He gives it to whom He wills."
