Giving Dawah according to a person’s temprament – Allamah Ibn Baaz
In the Name of Allah. Peace and blessings be upon the Messenger of Allah.
Indeed, Da`wah (calling to Islam) is one of the most important obligations of Islam. It is the practice of the messengers and their followers until the Day of Resurrection.
In fact, Allah (Exalted be He) has commanded people to practice Da`wah and praised those who do so.
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. [Surah Al-Nahl, 16: 125]
Allah (Exalted be He) also says: “And who is better in speech than he who says: “My Lord is Allâh (believes in His Oneness),” and then stands firm (acts upon His Order), and] invites (men) to Allâh’s (Islâmic Monotheism), and does righteous deeds, and says: “I am one of the Muslims.” [Surah Fussilat, 41: 33]
Dear reader, note how Allah (Exalted be He) commands Muslims in the first Ayah (Qur’anic verse) to practice Da`wah showing its many stages, so that a Da`y (caller to Islam) has a clear vision while calling different types of people.
 someone may be willing to do good but is heedless. This person needs to be invited wisely by showing him the Truth, guiding and inviting him to the immediate and deferred benefits of following it. In this case, he will accept the invitation and become heedful and hasten to follow the Truth.
 Another type of people may renounce the Truth and be preoccupied with other things; those people need fair preaching including some inspiration, disheartening and showing them the immediate and deferred benefits of following the Truth, as opposed to misery, corruption and bad consequences. This method may lead them to follow the Truth and abandon their false ways.
No doubt, this is a serious endeavor that requires the Da`y to show patience, forbearance and leniency with others, following the example of the best caller, Prophet Muhammad (peace be upon him).
 A third type of people is deluded with a doubtful matter which hinders him from understanding and following the Truth. This type needs to be approached and argued with in a good way to understand the Truth and remove doubts from their minds. A Da`y should be extra lenient with this type and must be patient when arguing with them until all doubts are removed by introducing various evidence and providing sufficient and clear explanation that agrees with the recipient’s language and customs.
Not everyone understands Arabic well, even if he is a scholar, for someone may be misguided in understanding a ruling due to having a different language, custom or tradition and this may lead to error and attributing words to Allah (Exalted be He) and His Messenger (peace be upon him) ignorantly.
You can imagine the great evils that may come out of such a behavior whether in this world or in the Hereafter. Therefore, the Da`y is in dire need of understanding the religion, grasping the rulings of Shari`ah (Islamic law) and knowing the languages and customs of those who are called to Allah (Exalted be He).
Thus, a Da`y should expand their knowledge about the Qur’an and Sunnah and exert every effort to understand the Commands of Allah (Exalted be He) and His Messenger (peace be upon him). Furthermore, they should master the Arabic language and the Sirah (the Prophet’s biography) from his mission until his death.
In this way, a Da`y will be able to guide people to the required Islamic morals and deeds in the Qur’an and Sunnah.
As much effort exerted and patience a Da`y shows, he will be praised by Allah (Exalted be He) Who says: “And who is better in speech than he who [says: “My Lord is Allâh (believes in His Oneness),” and then stands firm (acts upon His Order), and] invites (men) to Allâh’s (Islâmic Monotheism), and does righteous deeds” [Surah Fussilat, 41: 33]
This noble Ayah shows that callers to Allah are the best people in speech, if they support their words with righteous deeds and adhere to Islam out of love, true belief, and joy in this great blessing. Only in this case, will those, who are invited, be influenced by the Da`wah, benefit from it and love the callers for guiding them to the Truth.
On the other hand, there are callers whose deeds belie their speech.
They will not be praised by Allah and their Da`wah will yield no fruits. Rather, Allah hates them and people curse them and renounce their Da`wah. Allah (Exalted be He) says:
“O you who believe! Why do you say that which you do not do? Most hateful it is with Allâh that you say that which you do not do” [Surah Al-Saff, 61: 2-3]
Allah (Exalted be He) also reproaches the Jews saying: “Enjoin you Al-Birr (piety and righteousness and each and every act of obedience to Allâh) on the people and you forget (to practise it) yourselves, while you recite the Scripture [the Taurât (Torah)]! Have you then no sense?” [Surah Al-Baqarah, 2: 44]
In this Ayah, Allah (Glorified be He) shows us that a Da`y doing other than what they are preaching is not acceptable neither by reason nor by Shari`ah. How can any reasonable and religious person accept it?
O Allah! Guide us to what pleases You and let us be among those who are guided by the Truth and who apply it. You are the Most Generous One to be asked and the Best One to respond.
