On the authority Anas Bin Maalik who said that the Messenger of Allaah [ﷺ] said:
❝A slave’s Eemaan will not be honest and just until his heart is honest and just and his heart will not be honest and just until his tongue is honest and just. A man will not enter Paradise if his neighbour is not safe from his harm.❞
[Silsilah Ahadeeth As-Saheehah of Al-Albāni, (No. 2841) | Translated By Abbas Abu Yahya Miraath Al-Anbiyya]
