Question: Are all the Muslims sinful if none of them tried to see (look out for) the new moon of the beginning and ending of Ramadhaan?
Response: Trying to see (look out for) the new moon, whether it is the new moon of Ramadhaan or Shawwaal, is a well-known issue during the time of the companions. This is based on the statement of Ibn ‘Umar (radhi-yAllaahu ‘anhumaa):
«The people were looking for the new moon, so I informed the Prophet ﷺ that I had seen it, and he ordered the people to fast according to it»
And there is no doubt that the characteristics of the companions are more perfect and complete.
