Truthfulness

يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللهَ وَقُولُوا قَوْلًا سَدِيدًا يُصْلِحْ لَكُمْ أَعْمَالَكُمْ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ (33: 70-71)

Believers! Fear God and speak the truth. [As a result,] He will set right for you [the consequences of] your deeds and forgive your sins. (33:70-71)
