Allah Almighty says: {And if you ask his wives for something, ask them from behind a screen} [Surat al-Ahzāb: 53]
1628/1- ‘Uqbah ibn ‘Āmir (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “Beware of entering upon (non-mahram) women.” A man from the Ansār said: “O Messenger of Allah, what about the Hamw (brother-in-law)?” He said: “The Hamw is death itself.” [Narrated by Al-Bukhāri and Muslim]
Hamw: refers to the male relatives of the husband, such as his brother, nephew, or cousin.
1- Fitnah (temptation) is more likely to come from the husband’s male relatives than from others. This spotlights the risk arising from some families taking lightly of the matter of intermixing between the wives and the male relatives of their husbands. This is some of the plans of the devil for spreading immorality among Muslims.
2) The Shariah blocks the means of corruption within families and seeks to maintain purity of relationships among Muslim families.
1629/2- Ibn ‘Abbās (may Allah be pleased with him and his father) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “None of you should be alone with a woman except in the presence of a Mahram.” [Narrated by Al-Bukhāri and Muslim]
1) It is prohibited for a man to be alone with a non-Mahram woman, for this is one of the instigators of corruption and falling into temptation and immorality.
2) One has to keep away from the places of potential Fitnah and falling into sin, like unlawful intermixing and others.
1630/3- Buraydah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) said: “The sanctity of the wives of the Mujāhids (those who fight in the cause of Allah) to those who stay behind is like the sanctity of their own mothers. Any man, of those who stay behind, who looks after the family of a Mujāhid and betrays his trust (with regard to his wife) will be made to stand on the Day of Judgment before the Mujāhid who will take away from his good deeds as much as he likes until he is satisfied.” Then, the Messenger of Allah (may Allah’s peace and blessings be upon him) turned to us and said: “So what do you think (will he leave anything)?” [Narrated bt Muslim]
1) It is prohibited to betray the Mujāhids with regard to their wives, because they are the ones who support the religion and defend the sanctities of those who do not participate in Jihād.
2) A Muslim is required to save the honor of his Muslim brothers just like he saves his own honor. A believer to a believer is like the bricks of a wall, enforcing each other.
