Musnad Abu Ya'la al-Mawsili 237:3

Surayj ibn Yunus narrated to us, Yahya ibn Zakariyya narrated to us, from Isma'il, from Qays, who said: Khalid ibn al-Walid said: "There is no night in which a bride is gifted to my house whom I love, or in which I am given glad tidings of a boy, that is more beloved to me than a night of intense frost in a detachment of the Emigrants (Muhajirun), with which I reach the enemy at dawn."
