From Behind The Curtain.

Al Salamu 'Alaykum.

Maryam Bint Jahsh, a scholar of classical Arabic helped her husband, the Yemeni scholar Jamal Al-Deen ‘Ali Bin Abi'l-Fawaris Al-Hamdani resolve a debate with members of the Murji’ sect; while Al-Mutahhar ibn Muhammad who was married to the famous Mujtahidah Fatimah Bint Yahya used to consult her on juristic matters while she sat behind a curtain, such that when he came up with the answer, his students would say:

‘This is not from you. This is from behind the curtain!’
