فَصَبْرٌ جَمِيلٌ وَاللَّهُ الْمُسْتَعَانُ
So beautiful patience; and Allah is the One whose help is sought.
The compressed fa-ṣabrun jamīl is followed by wa-llāhu l-mustaʿān. The first points to patient endurance; the second locates the sought help with God. Naming Allah explicitly and using al-mustaʿān focuses attention on the source of help.
Two brief but complementary expressions bring human resolve and divine reliance together. The point is not that they share identical grammatical structures, but that their discourse functions cooperate.
