Arba'un 48 — four traits make a hypocrite

الأربعون 48 — أربع من كن فيه كان منافقاً

The hadith of Abdullah ibn Amr ibn al-As from the Prophet: 'four traits — whoever has them all is a hypocrite, and whoever has one of them has a trait of hypocrisy until he gives it up: one who when he speaks lies, when he promises breaks his word, when he disputes behaves wickedly, and when he pledges betrays' — the sixth of Ibn Rajab's added hadiths, transmitted by al-Bukhari (34, 2459, 3178) and Muslim (58) through al-A'mash from Abdullah ibn Murra from Masruq from Abdullah ibn Amr ibn al-As, both also carrying Abu Hurayra's report 'the hypocrite's sign is three: when he speaks he lies, when he promises he breaks his word, and when entrusted he betrays', Muslim's routes adding 'though he fast and pray and claim to be a Muslim' and 'among the hypocrite's marks are three'; Ibn Rajab records that a group leaning to irja' carried the hadith onto the hypocrites of the Prophet's own time — who lied to him when he spoke to them, betrayed him when entrusted with his secret, and broke their promise to march with him — Muhammad al-Muharram narrating this interpretation from Ata' as told him by Jabir from the Prophet, with al-Hasan said to have retracted to Ata's view when it reached him; Ibn Rajab calls this a lie, al-Muharram being a known lying shaykh — al-Bukhari declared his hadith repudiated and Yahya ibn Ma'in called him nothing (Jami' al-Ulum wal-Hikam pp. 901–913).
