Question: There is a [widespread] craze among the youth with mobile phones; they fill them with objectionable content – such as songs and music, as well as prohibited pictures. So what is your advice to the likes of these [youth], and may Allaah bless you?
Response: Regarding them, if they are [of an] old[er age]. then they must fear Allaah, and repent to Him from this behaviour; and they must remove [all of the prohibited material] from their mobile phones. [This prohibited material encourages] corruptive thoughts and ideas, [and is just for] amusement and play. And if they are young [in age], then their guardians must protect them from this [prohibited material] and prevent them from this harmful vain amusement, and from this behaviour which will prove harmful to them in the future.
