What is your advice for a student of knowledge regarding his calling to Allah (Mighty and Majestic) during his travel to his country for the vacation?

The questioner : The honorable Shaykh says: This question is on behalf of the students of knowledge. We are at the beginning of the summer vacation, preparing, and our other brothers, the students of knowledge, are preparing to call people to Allah in various parts of the earth, whether in our villages or elsewhere. So what is your advice for a student of knowledge in his calling to Allah (Mighty and Majestic)? What are the steps he should take? And what do you urge him to do?

The Shaykh : Yes, before anything else, a sincere intention. A person should intend with his calling to Allah (Mighty and Majestic) to spread the religion of Allah among the servants of Allah, to teach the ignorant, and to guide the misguided. This is before anything else.
Second, that he calls with wisdom, with gentleness, with softness, and with discussion in a calm manner if discussion is needed.
Third, that he does not intervene in a matter he does not understand, such as issuing a fatwa on something he has no knowledge of. For issuing a fatwa without knowledge is among the greatest of sins, because he speaks about Allah and fabricates against Allah. For this reason, Allah the Exalted compared it to shirk (associating partners with Allah) in His saying: So if he is asked about something he does not know, what should he say? He should say, "I do not know, but it is your right upon me that I ask and convey it to you," or he should direct them to someone they can ask, so that his conscience is cleared by that. However, I also say that if someone else is engaged in da'wah (calling to Islam) and his benefit from seeking knowledge is greater than his benefit from sermons and calling to Allah, let him continue seeking knowledge until he matures, and let him weigh the benefits, the benefit of this and the benefit of that.
