Engaging in da‛wah work is indisputably one of the best deeds in the sight of Allah and is highly commended in the Qur’an and the Prophet’s Sunnah. Evidence to this effect includes the following:
- Da‛wah is the means to success in this life and in the hereafter, as the Qur’an states, “Let there be a group among you who call others to good, and enjoin what is right, and forbid what is wrong: those who do this shall be successful.” (Soorat Aal ‛Imraan,3:104)
- No one has a better speech than that of those who engage in da‛wah activities. Commending such people, the Qur’an says, “Who speaks better than one who calls to Allah, does good works and says, ‘I am surely one of the Muslims.’?” (Soorat Fussilat, 41:33) It is clear, therefore, that there is no one whose speech is better than that of a person who calls people to the truth, for he is their guide to their Creator and Lord and the one who takes them out of the darkness of misguidance into the light of faith.
- Engaging in da‛wah work testifies to one’s compliance with Allah’s command: “Call to the way of your Lord with wisdom and fair admonition, and argue with them in the best manner possible.” (Soorat An-Nahl, 16:125) A person who dedicates himself to such a noble task must invite others to Islam with wisdom, making sure that he knows the personality of the people he wants to call to Islam so as to choose the best possible method to carry out the task, all the while arguing with them in the kindest, most gracious manner which appeals to them.
- Engaging in da‛wah work was the very task carried out by all of Allah’s messengers without exception, foremost of whom was Prophet Muhammad ﷺ, whom Allah sent to all mankind as a witness over people, giving news to the believers of immense reward in the hereafter, warning the unbelievers against severe punishment and spreading his light to all mankind. The Qur’an says, “Prophet, We have sent you as a witness, as a bearer of good news and a warner, and a caller to Allah by His permission and a light-giving lamp. Convey to the believers the good news that they will receive immense favour from Allah.” (Soorat Al-Ahzaab,33:45-47)
- Inviting people to Islam is the source of unlimited goodness; for each person you invite to Islam, you will get the same rewards for his prayer, worship and teaching others. What a great blessing Allah bestows on those who engage in da‛wah work! The Prophet ﷺ said, “Whoever calls to guidance will have a reward similar to that of those who follow it, without the reward of either of them being lessened at all.” (Saheeh Muslim: 2674)
- The rewardAllah has in store for those who invite others to Islam is far better than all the enjoyments of the present world, for such a reward is from Allah Himself, the Most Generous, who will recompense them abundantly for such a noble endeavour: “If you turn away from me, remember I ask no reward from you. Only Allah will reward me, and I have been commanded to submit completely to Him.” (Soorat Yoonus, 10:72)
The Prophet ﷺ also said in this respect, “If Allah guides one man through you, this will be better for you than possessing red camels.” (Saheeh Al-Bukhaaree: 2847; Saheeh Muslim: 2406) Camels were considered the most valuable property in ancient Arabia and the red variety was the most prized of all.
