the Messenger of Allah ﷺ said, "You must be truthful, for it leads to righteousness and they are both in Paradise. And beware of dishonesty, for it leads to wickedness and they are both in the Hellfire."  

قَالَ رَسُولُ اللهِ ﷺ «عَلَيْكُمْ بِالصِّدْقِ فَإِنَّهُ يَهْدِي إِلَى الْبِرِّ وَهُمَا فِي الْجَنَّةِ وَإِيَّاكُمْ وَالْكَذِبَ فَإِنَّهُ يَهْدِي إِلَى الْفُجُورِ وَهُمَا فِي النَّارِ»
