Riyad us-Salihin Hadith 572

Some of the poor Emigrants came to Messenger of Allah (ﷺ) and said to him, "The wealthy have obtained all high ranks and everlasting bliss." He asked, "How is that?" They replied: "They offer Salaah as we do, and observe Saum (fasting) as we do, but they give in Sadaqah (charity) and we do not, and they emancipate slaves and we cannot." He (ﷺ) said, "Shall I not teach you something whereby you will catch up with those who have preceded you and will get ahead of those who follow you, and no one will surpass you unless he does the same as you do?" They said, "Surely, O Messenger of Allah." He said, "Say: Subhan Allah, and Allahu Akbar, and praise Him (by saying Al-hamdu lillah) thirty-three times at the end of every Salaah." They returned to him and said: "Our brothers, the possessors of wealth, having heard what we are doing, have started doing the same." Messenger of Allah (ﷺ) said, "This is Grace of Allah which He gives to whom He wishes." [Al- Bukhari and Muslim].
