Is Shura / Consultation Wajib?
The context recounts the collective attributes of those who shall be granted the paradise. Quran 42:36-39 Translation by Muhammad Asad AND [remember that] whatever you are given [now] is but for the [passing] enjoyment of life in this world – whereas that which is with God is far better and more enduring. [It shall be given] to all who attain to faith and in their Sustainer place their trust; and who shun the more heinous sins and abominations; and who, whenever they are moved to anger, readily forgive; and who respond to [the call of] their Sustainer and are constant in prayer; and whose rule [in all matters of common concern] is consultation among themselves; and who spend on others out of what We provide for them as sustenance; and who, whenever tyranny afflicts them, defend themselves.
So how does it says wajib?
