Musnad Ahmed: Hadith 2326

Juwairiyah's name was Barrah (meaning righteous), but it was as if the Prophet (ﷺ) disliked that, so he named her Juwairiyah, because he did not like it to be said that he had left a righteous woman. He went out after he prayed, then he came back to her and she said: Since you left, O Messenger of Allah, I have continued in worship. He said to her: "After I left you, I said some words which, if they were to be weighed, would outweigh what you said: ‘Glory be to Allah as much as the number of His creation; glory be to Allah as much as pleases Him; glory be to Allah as much as the weight of His Throne; and glory be to Allah as much as the ink of His words.’”
