يَنْبَغِي أَنْ يَقْتَصِرَ مِنَ الْكَلَامِ عَلَى قَدْرِ الْحَاجَةِ حَذَرًا مِنَ اللَّغْوِ
Speech should be limited to what the need requires, so as to avoid needless wording.
A speaker's primary objective is to convey the intended information. If an uncomplicated report suffices, piling on emphatic devices may burden the sentence instead of improving it.
Yet the required measure does not invariably mean the fewest words. Strong denial may call for stronger reinforcement. The governing test is whether the expression serves its communicative situation.
