I heard the Prophet (ﷺ) saying, "Perform the bowing and the prostration properly (with peace of mind), for, by Him in Whose Hand my soul is, I see you from behind my back when you bow and when you prostrate."
Sahih al-Bukhari Book 83, Hadith 23
← Previous Hadith A man heard another man reciting: Surat-ul-Ikhlas (The Unity) 'Say: He is Allah, the One (112) and he was repeating it. The next morning he came to Allah's Messenger (ﷺ) and mentioned the whole story to him as if he regarded the recitation of that Sura as insufficient On that, Allah's Messenger (ﷺ) said, "By Him in Whose Hand my soul is! That (Sura No. 112) equals one-third of the Qur'an."

Sahih al-Bukhari Book 83, Hadith 22 Next Hadith → An Ansari woman came to the Prophet (ﷺ) in the company of her children, and the Prophet (ﷺ) said to her, "By Him in Whose Hand my soul is, you are the most beloved people to me!" And he repeated the statement thrice.
