Allah, the Most High said: "…and We chastise not (any people) until We raise an apostle (among them)." Holy Qur'an (Bani-Israel 17: 15) Then He addresses man, charging him with the responsibility of his destiny after the explanation and revelation has reached him, saying: "And indeed We caused the Word (of guid-ance) to come unto them continuosly, that they may be admonished." Holy Qur'an (Qasas 28: 51) Therefore, Allah, the Most High, introduced Himself to His servants, sent messengers to them, revealed messages and presented proofs and miracles: "…that there may remain any argument for people against Allah, after (the coming of ) these apostle,…" Holy Qur'an (Nisa' 4:165) From the foregoing, we can understand that the propagation of the Divine Message is among the most important and sacred obligations on this earth.
And its tasks are shared by the Sender of the message (Allah, the Most High), the Messenger and the one to whom the message is addressed i.e., man. Thus, it is clear that the call to Allah is initially the responsibility of the messengers and the prophets.
Thus, Allah addresses His Prophet, saying: "And call you unto the way of your Lord with wisdom and kindly exhortation and dispute with them in the manner which is the best; verily you Lord knows better of him who has gone astray from His path; and He knows best of those guided aright." Holy Qur'an (Nahil 166: 125) Just as the responsibility of propagation (or Tabligh) is initially that of the Messenger (s.a.w.), the Message of Islam has subsequently made it an obligation on every Muslim who believes in the Prophet (s.a.w.) and follows his guidance and footsteps.
It is the responsibility of every Muslim; not only the Holy Prophet (s.a.w.) alone. Allah, the Almighty, says: "Say you (O Our Apostle Muhammad): `This is my way, I invite ((you call) unto Allah; with clear sight, (which) I and he who follows me (possesses); and glory be to Allah, and I am not of the polytheists.'" Holy Qur'an (Yusuf 12: 108) However, the Holy Qur'an confirms that the responsibility of calling people to Allah is a joint venture between the Prophet and his followers, those who believe in Him down the Day of Re-surrection.
