[Machine] The Messenger of Allah ﷺ said, "Adhere to truthfulness, for indeed, truthfulness leads to righteousness, and righteousness leads to Paradise. Verily, a man speaks the truth until he is recorded by Allah as a truthful person. Beware of lying, for indeed, lying leads to wickedness, and wickedness leads to the Fire. Verily, a man lies until he is recorded by Allah as a liar." Abu Abdullah Al-Hafiz informed us, who was informed by Muhammad ibn Ya'qub, who was informed by Muhammad ibn Amr, who was informed by Yahya ibn Yahya, who reported it from Abu Muawiya, from Al-A'mash, mentioning it with his chain of narration, except that he said, "And a man continues to speak the truth and strive for truthfulness until he is recorded by Allah as a truthful person." And he said towards the end, "And a man continues to lie and strive for lying until he is recorded by Allah as a liar."

tirmidhi:1971Hannād > Abū Muʿāwiyah > al-Aʿmash > Shaqīq b. Salamah > ʿAbdullāh b. Masʿūd

"Abide by truthfulness. For indeed truthfulness leads to righteousness. And indeed righteousness leads to Paradise. A man continues telling the truth and trying hard to tell the truth until he is recorded with Allah as a truthful person. Refrain from falsehood. For indeed falsehood leads to wickedness, and wickedness leads to the Fire. A slave (of Allah) continues lying and trying hard to lie, until he is recorded with Allah as a liar."  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Ṣaḥīḥ.

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
ahmad:4108Wakīʿ Waʾabū Muʿāwiyah > al-Aʿmash > Abū Wāʾil > ʿAbdullāh

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)   

أحمد:٤١٠٨حَدَّثَنَا وَكِيعٌ وَأَبُو مُعَاوِيَةَ قَالَا حَدَّثَنَا الْأَعْمَشُ عَنْ أَبِي وَائِلٍ عَنْ عَبْدِ اللهِ قَالَ
