At-Tirmidhi also related on the authority of Ibn Mas'ud (RAA) that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said:“The believer is not a slanderer, nor does he curse others, and nor is he immoral or shameless.”Related by At-Tirmidhi who graded it to be Hasan. Al-Hakim graded it as Sahih and Ad-Daraqutni said that it is most probably Mawquf (traced only to a Companion).
