Jami` at-Tirmidhi Book 48, Hadith 228
“That I should say: ‘Glory is to Allah (Subḥān Allāh).’ ‘All praise is due to Allah (Al-ḥamdulillāh),’ ‘None has the right to be worshipped by Allah (Lā ilāha illallāh),’ and ‘Allah is the greatest (Allāhu akbar)’ is more beloved to me than all that the sun has risen over.”
“The Mufarridun have preceded.” They said: “And who are the Mufarridun, O Messenger of Allah (ﷺ)?” He said: “Those who absorb themselves in the remembrance of Allah, and remembrance removed their heavy burdens from them, until they will come on the Day of Judgement being light (in weight of their burdens).”
“There are three whose supplication is not rejected: The fasting person when he breaks his fast, the just leader, and the supplication of the oppressed person; Allah raises it up above the clouds and opens the gates of heaven to it. And the Lord says: ‘By My might, I shall surely aid you, even if it should be after a while.’”
