Riyad as-Salihin 689
'Abdullah bin 'Amr bin Al-'as (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "Four are the qualities which, when found in a person, make him a sheer hypocrite, and one who possesses one of them, possesses one characteristic of hypocrisy until he abandons it. These are: When he is entrusted with something, he betrays trust; when he speaks, he lies; when he promises, he acts treacherously; and when he argues, he behaves in a very imprudent, insulting manner." [Al-Bukhari and Muslim] .
وعن عبد الله بن عمرو بن العاص رضي الله عنهما، أن رسول الله صلى الله عليه وسلم قال‏:‏ ‏
"‏أربع من كن فيه كان منافقا خالصاً‏.‏ ومن كانت فيه خصلة منهن كانت فيه خصلة من النفاق حتى يدعها ‏:‏ إذا اؤتمن خان ، وإذا حدث كذب، وإذا عاهد غدر، وإذا خاصم فجر‏"‏‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
