'Itban bin Malik (May Allah be pleased with him) said in his long Hadith cited in the Chapter entitled 'Hope' reported:
When the Prophet (ﷺ) stood up to offer As-Salat (the prayer) he asked, "Where is Malik bin Ad-Dukhshum?" A man replied: "He is a hypocrite. He does not love Allah and His Messenger." The Prophet (ﷺ) said, "Do not say that. Do you not know that he said: La ilaha illallah (there is no true god except Allah),' seeking His Pleasure. Allah has made the fire of Hell unlawful for him who affirms that none has the right to be worshipped but Allah."[Al-Bukhari and Muslim].
