[Surah Al-Qalam 68:4]
Abdullah ibn Amr bin Al-As (May Allah be pleased with him) had a good knowledge of the Torah and Injeel. He used to say that there were many verses in these Books which foretold the advent of Mohammed ﷺ which were quite similar to those mentioned in the Qur’an.
He would not be sharp tongued or short-tempered - He would be gentle in speech. In Surah Aali Imran, verse 159, Allah mentions this quality of His Prophet ﷺ
"It is by the Grace of Allah that you are gentle with them, for, had you been harsh, they would have left you and fled."Surah Aali Imran: 159
He would not be among those who are loud and rowdy in the marketplaces.
Yelling, shouting or being loud is a part of a bad character. In Surah Luqman, the wise Luqman advises his son
"And keep your voice low, for the harshest of all the voices, is the voice of a donkey."Surah Luqman
This advice was given thousands of years before Qur’an was revealed. Allah liked it so much that He honored this advice by preserving it in His Book, the Qur’an. An entire Surah dedicated to a wise slave, is Surah Luqman.
A question arises; Why has the marketplace been mentioned here? We all have seen how people shout and fight in the markets and it looks quiet bad. Even a person with a cool temperament, may lose his temper while dealing in a market. The loudest place in any society is their markets. Aisha (May Allah be pleased with her) used to mention the same characteristics of her husband, though she had never read the Torah. Someone asked her once," What was the character of the Prophet ﷺ like?
She replied, "He was not obscene, nor did he ever crack an obscene joke. He never took revenge but preferred to forgive and let go."
A wife’s testimony of her husband’s character which has already been endorsed in divine books is indeed a great acknowledgement.
