Abu Malik Al-Ash'ari (may Allah be pleased with him) reported:
The Messenger of Allah ﷺ 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 ﷺ: "الطهور شطر الإيمان، والحمد لله تملأ الميزان، وسبحان الله، والحمد لله تملآن -أو تملأ- ما بين السماوات والأرض" ((رواه مسلم)).
