Sheikh Riyâd al-Musaymîrî, professor at al-Imâm University in Riyadh
I am glad to read about your concern for what would please your Lord, though you are young. May Allah bless you. I hope that, by the will of Allah, you will be a pious Muslim woman throughout your life and keep seeking knowledge and endeavoring to please your Lord.
Regarding your questions, these are the answers:
1. The purpose of wearing hijâb is, first and foremost, out of obedience to Allah and His Messenger (peace be upon him). Allah says: “And when you ask them for anything, ask them from before a screen.” One of the main objectives of hijâb is to safeguard women from the gazes of people of weak morals and from those seeking to indulge in unlawful worldly pleasures.
2. The benefits of hijâb are numerous. In addition to what I have already mentioned above, it protects the girl from being physically attacked or her reputation being injured. The Muslim woman is distinguished from the impious woman, for which she deserves respect.
Last but not least, hijâb also saves men from undergoing trials and temptations due to the beauty of women, just like the rules for modest male dress are there to save women from undergoing trials from the temptation of provocatively dressed men.
Modest dress that must be observed by men. Men are not allowed to wear shorts or wear tight fitting clothes. One of the reasons for this is that it protects women from temptation.
May Allah protect you and guide you.
