Spend time between waves obediently worshipping God .

This hadith speaks about the rewards that are given to those who are martyred at sea. It is said that they are like two martyrs on land, and those who suffer seasickness are like one who gets drenched in his own blood on land. The time spent between one wave and the next is seen as a lifetime spent in obedience to Allah, which is a great reward in itself. Furthermore, it is said that Allah has appointed the Angel of Death to seize souls except for those martyred at sea; instead, Allah Himself seizes their souls and forgives them all their sins as well as any debt they may have owed. This shows us how much reward there can be for sacrificing oneself in service to God even if it's something seemingly small such as seasickness or spending time between waves obediently worshipping Him.
