عَنْ أَبِي أُمَامَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ((يُطْبَعُ الْمُؤْمِنُ عَلَى الْخِلَالِ كُلِّهَا إِلَّا الْخِيَانَةَ وَالْكَذِبَ))
It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A believer can become accustomed to any kind of action, except for betrayal and lying.
