عَنْ عَبْدِ اللهِ بنِ مَسعُودٍ رضي الله عنه قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «عَلَيْكُمْ بِالصِّدْقِ، فَإِنَّ الصِّدْقَ يَهْدِي إِلَى الْبِرِّ، وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ، وَمَا يَزَالُ الرَّجُلُ يَصْدُقُ وَيَتَحَرَّى الصِّدْقَ حَتَّى يُكْتَبَ عِنْدَ اللهِ صِدِّيقًا، وَإِيَّاكُمْ وَالْكَذِبَ، فَإِنَّ الْكَذِبَ يَهْدِي إِلَى الْفُجُورِ، وَإِنَّ الْفُجُورَ يَهْدِي إِلَى النَّارِ، وَمَا يَزَالُ الرَّجُلُ يَكْذِبُ وَيَتَحَرَّى الْكَذِبَ حَتَّى يُكْتَبَ عِنْدَ اللهِ كَذَّابًا».
Kutoka kwa Abdallah bin Masoud -radhi za Allah ziwe juu yake- amesema: Amesema Mtume -rehema na amani ziwe juu yake-: Kutoka kwa Abdillah bin Mas'udi -radhi za Mwenyezi Mungu ziwe juu yake- Amesema: Amesema Mtume -rehema na amani ziwe juu yake-: "Shikamaneni na ukweli, kwani ukweli hupelekea katika wema, na hakika wema hupelekea katika pepo, na hatoacha mtu kuwa mkweli na akishughulika na ukweli mpaka ataandikwa kwa Mwenyezi Mungu kuwa ni mkweli, na tahadharini na uongo, kwani uongo unapelekea katika uovu, na hakika uovu hupelekea katika moto, na hatoacha mtu kuendelea kuwa muongo, na akishughulika na uongo mpaka ataandikwa mbele ya Mwenyezi Mungu kuwa ni muongo".
‘Abdullah ibn Mas‘ūd (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Adhere to truthfulness, for truthfulness leads to righteousness, and righteousness leads to Paradise. A man will keep telling the truth and strive to tell the truth until he is recorded with Allah as the most truthful. Beware of lying, for lying leads to wickedness and wickedness leads to Hellfire. A man will keep telling lies and strive to tell lies until he is recorded with Allah as a persistent liar."
