Is it permissible for an unmarried young man to mediate marriages between genders on Facebook, to speak with females for this purpose, and to allow them to speak with each other, given the presence of Sharia violations within the group?

The prevailing characteristic of groups and websites is a lack of discipline, and they can be a gateway to tribulation (fitnah), especially with the leniency in conversations between young men and women. If strict supervision and order can be established, and the tribulation is secured against, then there is no harm in overseeing them, provided that communication is limited to what is necessary, Islamic etiquette is observed, and everything that causes corruption, such as softness in speech, is prevented. This is in accordance with the Almighty's saying: "So do not be soft in speech [to men], lest he in whose heart is disease should covet, but speak with appropriate words." If tribulation is feared, then caution and safeguarding one's religion and honor become obligatory. It is recommended to hasten to marriage due to the worldly and hereafter benefits it entails.
