It is not uncommon for non-Muslims and even many Muslims to associate the Islamic commandments on Hijab with females, even though Islam has ordained Hijab for both men and women. In fact, many of us would be surprised to note that Allah states in the Holy Qur’an:
“Tell the believing men to cast down their looks and guard their private parts; that is purer for them; surely Allah is Aware of what they do. And tell the believing women that they cast down their looks and guard their private parts and do not display their ornaments except what appears thereof….” (24:30-31)
Indeed, before addressing women and telling them to conceal their bodies, Allah first addresses the believing men and tells us to lower our gaze!
It is impermissible for men to lengthen and trail their clothes below the ankles, even if it is not out of pride, as the Messenger of Allah (peace be upon him) forbade this and said in a Sahih (authentic) Hadith,
“Three persons whom Allah shall neither speak to on the Day of Resurrection, nor look at, nor purify, and they shall ha”ve a painful torment: he who lengthens and trails his Izar (garment worn below the waist) below the ankles, he who reminds (the people) of what he gives, and he who sells his merchandise by false swearing. Related by Muslim.”
“The Prophet (peace be upon him) also said, On the Day of Resurrection, Allah will not look at a person who drags his garment (behind him) out of pride.”
It is also impermissible for men to wear silk clothes; it is only permissible for women, according to the saying of the Prophet (peace be upon him), Gold and silk are permitted for the women of my Ummah (nation) and prohibited for men. However, if silk is worn as a treatment, such as in cases of itching or so, there is no harm in wearing it by men. The Prophet (peace be upon him) gave permission for Al-Zubayr and Talhah to wear silk clothes, as they had itching.
The ‘awrah of a man is the area between the navel and the knee; as for the navel and the knee themselves, they are not part of the ‘awrah.
Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:
There are several opinions concerning the matter:
One is that the knee is included in the ‘awrah so it must be covered.
The second opinion is that the navel and the knee are both part of the ‘awrah so they must both be covered.
The third opinion – which is the well-known view among our madhhab – is that the navel and the knee are not included in the ‘awrah, so they do not have to be covered. This is based on the definition of the ‘awrah as being “between the navel and the knee.”
