Quran 49:4 — The Walls (Al-Hujurat)

As for those who call on you from outside the walls, most of them do not understand.

[49:3] Surely, those who lower their voices at the messenger of GOD are the ones whose hearts are prepared by GOD to become righteous.* They have deserved forgiveness and a great recompense.

[49:5] Had they been patient until you came out to them, it would have been better for them. GOD is Forgiver, Most Merciful.
