Takyīf is from innovation

A man asked Imām Mālik رحمه الله about the statement of Allāh:

ٱلرَّحۡمَٰنُ عَلَى ٱلۡعَرۡشِ ٱسۡتَوَىٰ
The Most Merciful Istawá (rose) above the Throne.
– Sūrah Ṭā Hā, ʾĀyah 5

and said:

كيف؟

How?

Imām Mālik رحمه الله replied:

الاستواء معلوم، والكيف مجهول، والإيمان به واجب، والسؤال عنه بدعة

Istawá (rose) is known, the how is unknown, but believing in it is obligatory and asking about it is an innovation.
