Riyad as-Salihin, Book 16, Hadith 1413 (In-Book) ⓘ

Abu Malik Al-Ash'ari (may Allah be pleased with him) reported: The Messenger of Allah said: "Purity is half of iman (faith). ‘Al-hamdu lillah (all praise and gratitude belong to Allah)’ fills the scales, and ‘subhan-Allah (how far is Allah from every imperfection) and ‘Al-hamdulillah (all praise and gratitude belong to Allah)’ fill that which is between heaven and earth." [Muslim].

وعن أبي مالك الأشعري رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم‏:‏ ‏ "‏الطهور شطر الإيمان، والحمد لله تملأ الميزان، وسبحان الله، والحمد لله تملآن -أو تملأ- ما بين السماوات والأرض‏" ‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
