Is it valid for some of the brothers to strive in calling to Allah while justifying certain matters for themselves?

Question:
The questioner says that there are some brothers who strive in calling to Allah, but they may impose certain matters on themselves, such as going out for three days or doing other things they might do. Is this action correct? May Allah grant you success.

Answer:
Calling to Allah takes various forms: sometimes by coming to the mosque, calling people, and listening to the sermon; sometimes by giving advice in some gatherings; sometimes by writing and giving advice to be distributed to people; sometimes by traveling to a country for da'wah or to many countries. All of this is good. If the callers to Allah travel to a country for three days, ten days, or a month, this is a righteous deed. The Prophet (peace and blessings be upon him) sent callers to Allah; he sent callers to Yemen, and he sent callers to the Arabs, and he sent the seventy for da'wah, until what happened to them of killing occurred. Indeed, he sent callers to Allah; he sent Mu'adh to Yemen, and he sent Ali to Yemen, and he sent Abu Musa. He sent callers for a month, two months, a year, or two years; all of this is required. Rather, they should be people of the Sunnah, and they are people of innovation. If they are people of the Sunnah and people of insight, having knowledge, and they gather and disperse in the countries for calling to Allah, this one takes three days, this one ten days, and this one twenty days, cooperating with one another, then all of it is good. The Tabligh group's fault is not that they are three days and forty days; their fault is their ignorance of some of them. If there is someone who calls to Allah with insight, whether they are called Tablighi, callers, or otherwise, there is no harm. But the important thing is that they be on knowledge and insight. Allah the Exalted said: If they are on knowledge, whether they are from Jahinah or from Barai, or from such and such, men who traveled to al-Qasim for three days, and to Ha'il for three days, and to Makkah for four days, and to 'Afa for five days, and to al-Madinah for such and such, and to al-Sham for such and such, and to Egypt for such and such, all of it is good according to what they strove in. But it is obligatory for them to be on insight, having knowledge of what Allah said and what His Messenger said, what the Sunnah and the community were upon. They call to tawhid (the oneness of Allah), to the Sunnah, to obedience to Allah and His Messenger, and to abandoning sins. They are rewarded. This is from the Sunnah of the Prophet (peace and blessings be upon him) and the Sunnah of his successors, who sent callers. People need callers. And there is no harm if they specify days. What is the obstacle? The Prophet would go for a month, go for five days, go to Makkah for three days, go to Abha for three days, go to al-Qasim for ten days. There is no harm if they specify, so that they can get married and take with them what is sufficient for their needs. Yes.
