Is forming an advocacy group called "Youth of Awakening" (Shabab Al-Sahwa), organizing advocacy convoys, and distributing books with the aim of proselytizing to youth—while publicizing the group's name and contact information—considered unlawful (haram) and a violation of the prescribed methods of da'wah?

Collective work for the call to Allah is required and desirable, as long as it does not lead to blameworthy partisanship and fanaticism. The mere existence of a name like "Shabab Al-Sahwa" (Awakening Youth) is not problematic, as long as it does not lead to blameworthy partisanship. It is permissible to use modern means in calling to Allah, as long as they are not forbidden by Sharia, and "means are given the rulings of their ends."
