Sunan At-Tirmidhi
Hadith #2567
Abdullah bin Mas'ud narrated a Marfu' narration:""There are three whom Allah, the Mighty and Glorious, loves: A man who stood at night reciting the Book of Allah; a man who spent in charity with his right hand, concealing it""- it seems to me he said ""from his left hand""- ""and a man who was in a small expedition while his companions were decimated, yet he faced enemy."" Another chain reports a similar narration
