Footnotes
1 - Before Islām. After the ruling was revealed by Allāh, men were required to release those women unlawful to them (e.g., a stepmother, one of two sisters, or any wives over the limit of four). The same obligation applies to one once he has accepted Islām.
And do not marry women whom (maa means man) your fathers married, unless it be a thing of the past, which is forgiven you; surely that, marrying them, is obscene, vile, and abominable (maqtan, means it results in maqt, 'severe hate', from God), an evil way, [an evil] path is this.
