The harm these drugs incur is greater than their benefit; when harm prevails over benefit, the relevant matter is prohibited. A Muslim may resort to other alternatives that are more beneficial and free from side effects. Students can spread out their study hours and this is more effective to keep information by heart and help them understand it deeply, so they hardly forget it. Drivers can take rests at intervals during their long journeys, even if it takes them a little longer to cross the distance, but it will be safer for them, the passengers and those who share the road with them. Moreover, this greatly conforms to the rules of the traffic system.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
