To increase the number of Muslim who convey the message of Islam.
O thou wrapped up (in the mantle)! Arise and deliver thy warning! And thy Lord do thou magnify! And thy garments keep free from stain! And all abomination shun! Nor expect, in giving, any increase (for thyself)! But, for thy Lord’s (Cause), be patient and constant!
-Al-Qur’an: Surah Al-Mudhathir (74) ayah 1-4
