Drving around with people who break traffic laws
Some of my friends drive faster than they are allowed on their mopeds. According to the traffic laws of my country (a non-muslim country) they are only allowed to drive 30 km/hr, and they drive around 50 km/hr. These laws are obviously very strict, since this speed easily and legally can be achieved by someone on a bicycle. My friends do not drive irresponsibly to the point where they put other people in danger. Am I allowed to drive around with them?
Wa ʿAlaykumus Salām Wa Raḥmatullāhi Wa Barakātuh
The Sharī’ah strongly advises against reciprocating harm just as much as one should avoid causing harm, therefore, to refrain from being seated on or in a motor vehicle with those who have the potential of putting your life at risk or the lives of others, in which case you may consider talking to them and encouraging them to be responsible and to look after the many bounties granted to them by Allāh ﷻ such as a motor vehicle, good health, life, etc.
Also, not to reciprocate harm in the sense case where such action would bring about any form of legal consequences upon yourselves such as a criminal offense which has its own implications or being served a traffic fine which one has to settle from his own lawful wealth.
Apart from the aforementioned, there will be no prohibition from the side of the Shari’ah in doing so.
