Abu Umama reported,

Abu Umama said, "The Messenger of Allah ﷺ set out on a military expedition, so I came to him and said, 'Messenger of Allah, ask Allah to grant me martyrdom.'He said, 'Allah, keep them safe and grant them spoils.'So we came back safe and with spoils. Then the Messenger of Allah ﷺ set out on a second expedition, and I came to him and said, 'Messenger of Allah, ask Allah to grant me martyrdom.'He said, 'Allah, keep them safe and grant them spoils.'Then he set out on a third expedition, and I came to him and said, 'Messenger of Allah, I came to you twice before this time and asked you to ask Allah to grant me martyrdom, and you prayed to Allah to keep us safe and grant us spoils, and we came back safe and with spoils. Messenger of Allah, ask Allah to grant me martyrdom.'He said, 'Allah, keep them safe and grant them spoils.'So we came back safe and with spoils. Then I came to him and said, 'Messenger of Allah, command me to do some deed.'He said, 'Hold fast to fasting, for nothing equals it.'"After that, Abu Umama, his wife, and his servant were never seen except fasting. If smoke was ever seen rising from their house during the day, people would say, "A guest has come to them," or "Someone has arrived and is staying with them."He continued like that as long as Allah willed, then he said, "I came to him and said, 'Messenger of Allah, you commanded us to fast, and I hope Allah has blessed us in it. Messenger of Allah, command me to do another deed.'He said, 'Know that you will not perform a single sajdah before Allah without Allah raising you a degree by it and erasing a sin from you by it.'"
