Ma'arif al-Qur'an 经注： Maryam 阿雅 88

مَنِ اتَّخَذَ عِندَ الرَّ‌حْمَٰنِ عَهْدًا

"Except the one who has taken a covenant with the Rahman (All-Merciful) " - 19:87.

Sayyidna Ibn ` Abbas ؓ has said that عَھد means a declaration of firm belief in the Unity of Allah Ta’ ala, while others say that عِھد means committing the Qur’ an to memory. In brief only those people will have the permission to intercede with Allah who stand firm by their covenant to adhere to the true faith. (Ruh)
