Abdul Razzaq al-Badr said,
The quality of haya’ is an attribute that brings forth nothing but good and it is one of the parts of imān. It induces the person to do the good in all of his affairs, be it related to worship, etiquettes or social life. It also keeps the person away from the ugly sins, wrongdoings and ill-manners.
358. Abū Sa’īd al-Khudarī narrated: “The Prophet (peace be upon him) was the most modest, more so than a virgin in her private quarters. If he did not like something, we could notice that on his face.” [416]
Ibn Hajar al-Asqalānī said,
Al-Qadī ‘Iyyād said, “Shyness and modesty were made part of imān though it is a human instinct. For a characteristic to fall in line with the guidelines of religion [rather than being a mere human instinct], one would need to establish the intention, endeavour and possess the knowledge to do so. As for stating that shyness brings about nothing but goodness, it is found problematic because someone may argue that sometimes shyness prevents one from facing and stopping a wrongdoer or not fulfilling rights and obligations. The answer to this is that there are two types of shyness; one that conforms to religion and that does not lead to the aforementioned weakness whilst the other type is given the same name (i.e. shyness) because it shares the trait of preventing one from low and ugly acts.
Abū al-‘Abbās al-Qurtubī said that cultivated shyness is the type of shyness that Allāh has made part of imān and the characteristic that people ought to acquire. However, the instinctual type of shyness could support the attained shyness and it could integrate with the attained shyness until the prescribed shyness becomes an innate nature and the Prophet (peace be upon him) enjoyed both types; his instinctual shyness made him more modest than a virgin girl in her private quarters and his attained shyness elevated him to the highest status.
359. Aisha reported: “I never looked towards the private parts of the Messenger of Allāh (peace be upon him), [or she said] that I never saw the private parts of the Messenger of Allāh (peace be upon him).” [417]
Ibn Hajar al-Haytamī said,
This hadīth manifests the perfect level of shyness possessed by the Prophet (peace be upon him) because he did not do anything that would allow her to look at his private parts. This is because a woman would not dare to see the private parts of her husband unless he would allow it and give his consent.
