Narrated Aslam bin 'Imran At-Tujibi: "We were in a Roman city, when a large column of Romans came out to us. So about the same number or more of the Muslims went towards them. The commander of the people of Egypt was 'Uqbah bin 'Amir, and the commenter of the (our) group was Fadalah bin 'Ubaid. One man among the Muslims reached the Roman line until he entered amidst them, so the people started screaming: 'Subhan Allah! He has thrown himself into destruction!' Abu Ayyub Al-Ansari said: 'O you people! You give this interpretation for this Ayah, while this Ayah was only revealed about us, the people among the Ansar, when Allah made Islam might, and increased its supporters. Some of us secretly said to each other, outside of the presence of the Messenger of Allah (ﷺ): "Our wealth has been ruined, and Allah has strengthened Islam, and increased its supporters, so if we tend to our wealth then what we lost of it shall be revitalized for us." So Allah, Blessed and Most High, revealed to His Prophet (ﷺ), rebuking what we said: 'And spend in the cause of Allah, and do not throw yourselves into destruction. (2:195)' So the destruction was tending to the wealth and maintaining it.' Abu Ayyub did not cease traveling in Allah's cause, until he was buried in the land of the Romans."
