Swahilli buts its a somali city in kenya.Idk anything about Garissa, what's their official language?
Nayahe i can swear you have some sort of fetish''Shieks'' who falsely inform the public to enforce stupid rules like that deserve non other than to be castrated.
If the ruling is not based in the Quran and Hadith it is invalid.
There is nothing to indicate that this is haram. As long as there is a Male guardian to travel with them it's cool.
