Sahih Bukhari | Volume 9 | Hadith Number 71
Narrated by 'Itban bin Malik
Once Allah's Apostle came to me in the morning, and a man among us said, "Where is Malik bin Ad-Dukhshun?" Another man from us replied, "He is a hypocrite who does not love Allah and His Apostle." The Prophet said, "Don't you think that he says: None has the right to be worshipped but Allah, only for Allah's sake?" They replied, "Yes" The Prophet said, "Nobody will meet Allah with that saying on the Day of Resurrection, but Allah will save him from the Fire."
