Observe fast on special days like ashurah , strive for excellence in acts of worship , fulfill your religious obligations .

The Prophet Muhammad taught his followers to observe fast on the day of Ashura. This is a special day for Muslims as it marks the anniversary of Moses and his people being saved from Pharaoh. It is also believed that this was the day when Allah saved Prophet Noah and his people from drowning in a great flood. The Prophet Muhammad encouraged his followers to observe fast on this day as an act of worship and remembrance. However, when fasting during Ramadan became obligatory, he no longer commanded them to do so or was particular about it. This teaches us that while we should strive for excellence in our acts of worship, we should not neglect our obligations either. We must remember that Allah has given us certain obligations which must be fulfilled first before striving for excellence in other acts of worship such as voluntary fasting or charity work etc.
