19 Preface مَرَجَ البَحرَينِ يَلتَقِيانِYusuf AliHe has let free1 the two bodies of flowing water, meeting together:See 25:53 and nn. 3111-3112, where it is explained how the two bodies of water, salt and sweet, meet together, yet keep separate, as if there was a barrier or partition between them. This is also one of the favours of God. Sea water is a sanitating agent, while fresh water is sweet and palatable to drink. For the allegorical interpretation, see notes 2404-2405 to 18:60; also n. 5186 (end) below.
