The poor Emigrants came to the Messenger of Allah (ﷺ) and said: "The wealthy have gone with the highest ranks and lasting bliss." He asked: "How is that?" They replied: "They offer Salat (prayer) as we offer it; they observe fast as we do; (and as they are wealthy) they perform Hajj and 'Umrah, and go for Jihad, and they spend in charity but we cannot, and they free the slaves but we are unable to do so." The Messenger of Allah (ﷺ) said, "Shall I not teach you something with which you may overtake those who surpassed you and with which you will surpass those who will come after you? None will excel you unless he who does which you do." They said: "Yes, please do, O Messenger of Allah" He (ﷺ) said, "You should recite: Tasbih (Allah is free from imperfection), Takbir (Allah is Greatest), Tahmid (Praise be to Allah) thirty-three times after each Salat."

[Al-Bukhari and Muslim].

Abu Salih, the subnarrator of the Hadith said, when Abu Hurairah (May Allah be pleased with him) was asked about the manner of reciting Tasbih, Tahmid and Takbir, he said, "Recite: "Subhan-Allah, wal-hamdulillah, wallahu Akbar', till all are recited thirty-three times.
