The ringtones of my mobile phone are based on music so can I use Islamic music ringtones like Tala al Badru Alaina....etc.

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

If the Anasheed (Islamic Rhymes) are free from the expressions that are contrary to Islamic Shariah and do not contain music then they are allowed.

Allah knows best.
