truth

Lying is the source of other vices; therefore, it is strongly condemned in Islamic teachings. 

وَقُلْ جَاءَ الْحَقُّ وَزَهَقَ الْبَاطِلُ، الاسراء:81

وَلَا تَلْبِسُوا الْحَقَّ بِالْبَاطِلِ وَتَكْتُمُوا الْحَقَّ وَأَنْتُمْ تَعْلَمُونَ، البقرة:42

We think that the goal of life is truth, that is, Allah.

Introducing the truth is more helpful than introducing the people of truth, as Imam Ali (A) did the same guiding one of his companions.
