Is it permissible for men to give up their seats on public transport for unveiled women out of chivalry, or is that considered participation in sin, and should they be left standing?

The Islamic Sharia came to achieve and perfect benefits, and to disable and diminish harms, prioritizing the better of two good things and repelling the greater of two harms by enduring the lesser.

Based on this, the issue of a man standing up for a woman who is dressed immodestly (mutabarrijah) in public transport is divided into three cases:

1. If your standing up achieves a benefit and lessens harm: Such as her remaining standing among men being a source of temptation (fitna), or her sitting leading to a reduction of evil, or softening her heart towards commitment (to religious observance). 2. If your standing up leads to harm: Such as being exposed to physical contact or looking at women. In this case, you must remain in your place. The Permanent Committee has issued a fatwa to this effect. 3. If matters are equal and there is no harm in your standing up or remaining seated: The matter is broad. Your standing up for her is considered chivalry and good manners, and it is not considered aiding in sin or condoning evil. This is because vacating a seat for a woman or for the weak is a common practice among people, regardless of her immodest dress.
