Hadith text
Narrated Abu Said Al-Khudri: A man heard another man reciting (Surat-Al-Ikhlas) 'Say He is Allah, (the) One.' (112. 1) repeatedly. The next morning he came to Allah's Messenger (ﷺ) and informed him about it as if he thought that it was not enough to recite. On that Allah's Messenger (ﷺ) said, "By Him in Whose Hand my life is, this Surah is equal to one-third of the Qur'an
Abu Saeed Al-Khudri bataate hain: Ek shaks ne doosre shaks ko Surah Al-Ikhlas, 'Kaho: Wo Allah ek hai' (112:1), baar baar padhte suna. Agli subah wo Nabi (SAW) ke paas aaya aur unhein iski khabar di, jaise use laga ke sirf isi ko padhna kaafi nahi hai. Isper Allah ke Rasool (SAW) ne farmaya, 'Us Zaat ki qasam jiske haath mein meri jaan hai, ye Surah Quran ke tihaai hisse ke barabar hai.'
