(a) Amr bin Abi Salamah said: I asked Ibn Thawban: Is the iqamah required of women? He said: His father narrated from Makhul: If they give the adhan and the iqamah, that is better, and if they do no more than the iqamah, it suffices them. Ibn Thawban said: Even if they do not give the iqamah.
(b) It is narrated from Sayyidah Aishah (may Allah be pleased with her) that we used to pray without iqamah.
