Follow what you can see with your own eyes rather than relying on hearsay or assumptions when determining religious obligations such as fasting and performing other rituals related to worshiping Allah SWT .

This hadith emphasizes on following the sighting of the moon in order to determine when to fast and perform religious rites. It is narrated by 'Abdur-Rahman bin Zaid bin Al-Khattab who was a companion of Prophet Muhammad ﷺ. If there is doubt as to whether or not a month has begun then it should be determined by witnesses who have seen it with their own eyes. If two witnesses testify that they have seen it then fasting should begin and end accordingly. However if there are no witnesses then thirty days should be completed before fasting begins again. This hadith teaches us that we must follow what we can see with our own eyes rather than relying on hearsay or assumptions when determining religious obligations such as fasting and performing other rituals related to worshiping Allah SWT.
