Avoid falsehood, for falsehood leads to wickedness, and wickedness to hell; and if a man continues to speak falsehood and makes falsehood his object, he will be recorded in Allah’s presence as a great liar. And adhere to truth, for truth leads to good deeds, and good deeds lead to paradise. If a man continues to speak the truth and makes truth his object, he will be recorded in Allah’s presence as eminently truthful. (Using translation from Abū Dāʾūd 4989)
قَالَ رَسُولُ اللهِ ﷺ إِيَّاكُمْ وَالْكَذِبَ فَإِنَّ الْكَذِبَ يَهْدِي إِلَى الْفُجُورِ وَالْفُجُورَ يَهْدِي إِلَى النَّارِ وَإِنَّ الرَّجُلَ لَيَكْذِبُ حَتَّى يُكْتَبَ عِنْدَ اللهِ كَذَّابًا وَقَالَ قَالَ النَّبِيُّ ﷺ عَلَيْكُمْ بِالصِّدْقِ فَإِنَّ الصِّدْقَ يَهْدِي إِلَى الْبِرِّ وَإِنَّ الْبِرَّ يَهْدِي إِلَى الْجَنَّةِ وَإِنَّهُ يَعْنِي الرَّجُلَ لَيَصْدُقُ وَيَتَحَرَّى الصِّدْقَ حَتَّى يُكْتَبَ عِنْدَ اللهِ صِدِّيقًا قَالَ أَبُو مُعَاوِيَةَ وَمَا يَزَالُ الرَّجُلُ يَصْدُقُ وَيَتَحَرَّى الصِّدْقَ
