When he was told that the Kharijites had crossed the bridge of Nahrawan

قال الشريف: يعني بالنطفة: ماء النهر، وهي أفصح كناية عن الماء وإن كان كثيراً جماً، وقد أشرنا إلى ذلك فيما تقدم عند مضيّ ما أشبهه.
as-Sayyid ar-Raḍī says: In this sermon “nuṭfah” implies the River Euphrates, and for water this is the nicest expression even though water may be much.
