Da`wah to the cause of Allah is Tawqifiy from one side and Tawfiqy from the other side

Q 2: Is Da`wah (calling to Islam) Tawqifiyah (bounded by a religious text and not amenable to personal opinion) and what determines its success?

A: Da`wah is Tawqifiyah in that the Da`y (caller to Islam) should follow the Manhaj (methodology) that Allah guided to. The Da`y to Allah should perform their Da`wah with wisdom and good exhortation. They should approach discussions on issues subject to Ijtihad (juristic effort to infer expert legal rulings) in the best manner, in order to reach the truth, and not with the aim of refuting the arguments of others or showing bigotry in their opinions. Allah (Exalted be He) says: Invite (mankind, O Muhammad صلى الله عليه و سلم) to the Way of your Lord (i.e. Islâm) with wisdom (i.e. with the Divine Revelation and the Qur’ân) and fair preaching, and argue with them in a way that is better. (Part No. 3; Page No. 380) If a Da`y is able to change detestable situations by themselves, they should do so, but if they cannot, they should speak out against them, but if they cannot do that, then they should hate it in their heart, as this is the weakest form of Iman (faith). This is a collective duty, which if it is done by some, the responsibility for it will be removed from the others, but it is incumbent on those who are able to do so.In relation to its success, this is determined by Allah and it is He Who determines who will perform the obligation of Da`wah successfully and it is He Who will open their heart to it and prepare them to do it through His Bounty and Mercy.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
