THE ORIGINS OF THE ISLAMIC STATE
The Moslems also attacked Ḥiṣn Malîḳiya, which was a watching post, and reduced it. They drove the Persians from other watching posts at aṭ-Ṭaff, the Persians by this time having become emaciated and having become weak and feeble in power. Certain Moslems crossed Nahr [canal] Sûra and came to Kûtha, Nahr al-Malik and Bâdûraiya; some reaching as far as Kalwâdha. The Arabs in these razzias lived on what they plundered.
There are those who say that between the battles of Mihrân and al-Ḳâdisîyah, 18 months elapsed.
