Most people before them went astray too.
Numbers are not proof
Ibn Kathir says Allah tells us that most of the previous nations went astray, worshipping other gods alongside Him. For the small, persecuted group of Muslims in Makkah, this was comfort: being few was nothing new.
You are the only one at the office who does not join in. The only one in the family who prays on time. It feels lonely, and you wonder if you are wrong. Being outnumbered has never decided what is true.
If most people do it, it is probably fine.
Most people have been wrong before. I check the path, not the crowd.
Think of one good thing you do that few around you do. Keep doing it today, quietly.
