Hazrat Ibn Abbas (may Allah be pleased with them both), in the explanation of the verse of the Holy Qur'an { وَأَخَذْنَ مِنْکُمْ مِیثَاقًا غَلِیظًا }, says that it means to keep (the wife) with kindness (to live together in a good manner) or to release (her) with goodness (to let her go in a good way).
