و عن أبي بكرة نفيع بن الحارث رضي الله عنه
قال: قال رسول الله صلى الله عليه وسلم: «ألا أنبئكم بأكبر الكبائر؟ «ثلاثًا قلنا: بلى يا رسول الله: قال: «الإشراك بالله، وعقوق الوالدين«وكان متكئاً فجلس، فقال: «ألا و قول الزور و شهادة الزور«فما زال يكررها حتى قلنا: ليته سكتز»
Messenger of Allah (sallallahu alayhi wa sallam) said, “Shall I not inform you of the biggest of the major sins?” Messenger of Allah (sallallahu alayhi wa sallam) asked this question thrice.
We said, “Yes, O Messenger of Allah. (Please inform us.)”. He said, “Ascribing partners to Allah, and to be undutiful to your parents”. Messenger of Allah (sallallahu alayhi wa sallam) sat up from his reclining position and said, “And I warn you against giving forged statement and a false testimony; I warn you against giving forged statement and a false testimony”.
Messenger of Allah (sallallahu alayhi wa sallam) kept on repeating that warning till we wished he would stop.
