The Al-Shabab Mujahideen are probably the only group that is helping the Somali people in terms of establishing law and order in a land where anarchy exists. I haven’t read or even seen anything from any of the moderate Sufi scholars or websites regarding the destruction of these Sufi shrines.
Edit: I just want to make it clear that I do not support the destruction of the graves of Muslims.
Edit 2: Although many Somalians may appreciate the work that the Al-Shabab are doing in Somalia they still praise Al-Qaeda and are linked with them (via their videos) who are extremist Muslim and have deviated by the majority of the scholars of the ummah.
Allah knows best. May Allah (swt) forgive us all and guide us all.
