Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن عبد الله بن عمرو بن العاص رضي الله عنهما أن رسول الله صلى الله عليه وسلم قال: " أربع من كن فيه، كان منافقًا خالصًا، ومن كانت فيه خصلة منهن، كان فيه خصلة من النفاق حتى يدعها: إذا اؤتمن خان، وإذا حدث كذب، وإذا عاهد غدر، وإذا خاصم فجر" ((متفق عليه)).
The Messenger of Allah (ﷺ) said, "Whosoever possesses these four characteristics is a sheer hypocrite; and anyone who possesses one of them possesses a characteristic of hypocrisy till he gives it up. These are: when he is entrusted with something, he proves dishonest; when he speaks, he tells a lie; when he makes a covenant, he proves treacherous; and when he quarrels, he behaves in very imprudent, evil, insulting manner."[Al-Bukhari and Muslim].
