In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Anas Ibn Malik [may Allaah be pleased with him] said that the Prophet [peace and blessings of Allaah be upon him] said, “Make things easy (i.e. within the boundaries of halaal and haraam) and do not make things difficult. Give glad tidings and do not frighten them (i.e. the people) away”. [Saheeh Al-Bukhaari. Hadeeth Number 69]
Firstly, everyone agrees with the fact that unless exempt, everyone must obey the law and wear a mask in places where it has been mandated, even if one disagrees with the science.
Secondly, as for demanding that people must wear masks in other than places mandated by the government, then indeed you should expect that some of us people will critically question your stance with a rebuttal.
Perhaps the following statement of Imaam Al-Albaanee [may Allaah have mercy upon him] transmitted by Shaikh Abu Khadeejah [may Allaah preserve him] is enough to deal with what you harbour in your heart. Al-Imām Al-Albāni (rahimahullāh) said: “I know many doctors who do not shake hands with people fearing that there might be an infectious microbe in the hand of the person. For this reason, they do not shake hands with people–and this is a waswasah, a whispering… the whisper [is normally] restricted to some of the worshippers, but it has passed on to other than the worshippers, to the doctors and their likes…
So the meaning is that this is a whispering which destroys personal ties and human relations which are established between people. The foundation is that every person’s left-overs and interaction with them is that he is upon fiṭrah (original disposition) and upon health and wellbeing.
Thus, when it is established that so-and-so, for example, Allāh forbid, has the disease of tuberculosis and drinks from a vessel, then you can keep away from this, but you should have certain knowledge [beforehand] that he is afflicted with the disease of tuberculosis.
As for a whisper, “maybe he has it, maybe he has it”, then this is not permissible, because this is having an evil opinion about your Muslim brother and secondly, it comprises cutting off ties of brotherhood between you and your Muslim brother.
But when it is verifiably established that he is afflicted [with the disease], then you can take precautions and avoid drinking [from the same vessel] and shaking his hand. This is not from the whisperings and nor is it absence of reliance upon Allāh as is claimed by some people.” [End of quote]:
Harmonising between the Prophet’s negation of contagious diseases and his forbiddance of entering a land which has a contagious disease, mixing with afflicted people and touching them―Imām Ibn Bāz, Imām Al-Albāni and Al-Hāfidh Ibn Hajr
Harmonising between the hadīth, “There is no contagious disease” and, “Flee from the leper as you would from the lion.” ―Imām Al-Albāni and Imām Ibn Bāz
Therefore, do not be overbearing in the gatherings.
