Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"And (it is also for) those who, before them, had homes (in Al-Madīna) and had adopted the Faith..." (V.59:9)
Narrated `Umar:
I recommend that my successor should take care of and secure the rights of the early emigrants; and I also advise my successor to be kind to the Ansar who had homes (in Medina) and had adopted the Faith, before the Prophet (ﷺ) migrated to them, and to accept the good from their good ones and excuse their wrong doers.
