The Peak of Eloquence · Hadith 204 (#Passage #4)
Chapter 48 | At the time of marching towards Syria
قال السيد الشريف: أقول: يعني عليه السلام بالملطاط ها هنا: السّمْتَ الذي أمرهم بلزومه، وهو شاطىء الفرات، ويقال ذلك أيضاً لشاطىء البحر، وأصله ما استوى من الاَرض. ويعني بالنطفة: ماء الفرات، وهو من غريب العبارات وعجيبها.
as-Sayyid ar-Raḍī says: Here by “milṭāṭ” Amīr al-mu’minīn has meant the direction where he had ordered the men to camp and that was the bank of the Euphrates, and “milṭāṭ” is used for the bank of a river although its literal meaning is level ground whereas by “nuṭfah” he means the water of the Euphrates, and these are amazing expressions.
