Think before You Speak
Al-Ḥāfiẓ Al-Nawawī, may Allāh have mercy on him, said:
Whoever wants to say a word or a sentence should think to himself about the consequences of that before saying [anything]; then if the advantages of [doing so] become clear, he speaks; otherwise, he holds off.
Sharḥ Ṣaḥīḥ Muslim, vol. 18., p. 117.
