Gusse mein na sunana Rahu teen wale ko koi baat, ek ki teen sunaega. Behas mein pada jo iske saath, shartiya tu haar jaega.
Do not say anything in anger to the one with Rahu in the 3rd, he will reply with three for every one. Whoever gets into an argument with him, will surely lose.
The 3rd house rules communication, courage, and the throat. Rahu is the planet of extremes, aggression, and breaking limits.
When Rahu sits in the 3rd house, it creates a person with a razor-sharp, aggressive tongue. Dr. Sharma gives a clear warning: Never speak to this person in anger. If you say one harsh word to them, they will fire back with three ("ek ki teen sunaega").
They are absolute masters of verbal combat. If you get into an argument or debate with them, it is a guarantee ("shartiya") that you will lose. They will verbally destroy their opponents.
