There is a matter that most people do not understand. An act’s “not being from sunnah” is one thing and its being “against sunnah” is another. These two are different. For instance, using electronic appliances is not from sunnah. Now if a person says using electricity or using electric fan is “against sunnah” it will be wrong. An act shall be termed as “against the sunnah” if the Messenger of Allah ﷺ had advised doing it even if only as a recommendation (mustahab). In such a case if a person leaves that act and does otherwise it shall be “against the sunnah.” And whatever act will be “against sunnah” it will be reprehensible (makruh) at least. But if there is something that the Messenger of Allah ﷺ did not do and a person does that it shall not be termed as something “against the sunnah.” For instance, it is reported in a hadith that never was a well baked thin-bread (khubz) prepared for the Messenger of Allah ﷺ nor did he eat it in a small plate (sukrujah). It does not mean eating thin-bread or eating it in a small plate is “against sunnah.” Rather, it shall be said that the act is “not from sunnah” and an act’s being “not from sunnah” does not necessitate its being “against the sunnah” … Therefore, everything should be understood in its due context and it is not right to exaggerate it.
