Maulana Abul Kalam AzadThe Tarjuman al-Qur’an1968

The Qur’an uses the term Itqan also to denote the very same thing. It means that everything in the Universe is properly set and there is no defect or flaw noticeable in its setting.

“Tis the work of God who sets everything with exactitude.”

Surah: Al-Naml (The Ants) – Chapter: 27 – Verse: 88
