الْأَنَاةُ مِنَ اللَّهِ
Meaning: Deliberation is from Allah.
الْأَنَاةُ is the subject (mubtadaʾ), the quality being discussed. مِنَ اللَّهِ is a prepositional expression (jār and majrūr) functioning as the predicate (khabar): it says where that quality comes from.
وَالْعَجَلَةُ مِنَ الشَّيْطَانِ follows the same construction. The وَ connects the two contrasting statements. In this context مِنْ means “from,” not “one part of.”
Notice how the same brief sentence pattern presents two opposing qualities clearly.
