Shu'bah bin al-Hajjaj شعبة بن الحجاج · The Book of Jihad

"Whoever dies without having fought or thought of fighting, he dies on one of the branches of hypocrisy."

"A man asked the Messenger of Allah (ﷺ) which deed is best. He said: 'Faith in Allah.' He said: 'Then what?' He said: 'Jihad in the cause of Allah.' He said: 'Then what?' He said: 'Hajjun Mabrur.'" Hajj, that is accepted, or free of sin.

"The Messenger of Allah (ﷺ) said: 'Whoever equips a warrior has fought, and whoever looks after his family in his absence has fought.'"

"The Messenger of Allah (ﷺ) said: 'Whoever spends on a pair (of things) in the cause of Allah, the gatekeepers of Paradise will call him from the gates of Paradise (saying): O So-and-so, come and enter!' Abu Bakr said: 'O Messenger of Allah, such a person will never perish or be miserable.' The Messenger of Allah (ﷺ) said: 'I hope that you will be one of them.'"
