قُولوا للناسِ أحسَنَ ما تُحِبُّونَ أن يُقالَ لَكُم؛ فإنَّ اللّهَ يُبغِضُ اللَّعّانَ السَّبّابَ الطَّعّانَ علَى المؤمنينَ، الفاحِشَ المُتَفَحِّشَ، السائلَ المُلحِفَ.
Imam Muhammad al-Baqir (as):
Say unto people the best of what you would like them to say to you, for Allah hates the curser, swearer, and slanderer of believers, the user of obscene language and to do it shamelessly, and the importunate beggar.
