Al-Matalib al-'Aliyah 397 — The rows

It is narrated from Hujayrah bint Husayn (may Allah have mercy on her) that "the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), led us in the Asr prayer, and she stood among us (that is, in the middle of the first row, instead of standing forward on the prayer spot like a male imam)."
The chain of this narration is hasan (good); Imam Musaddad narrated it in his Musnad and Imam Ibn Abi Shaybah in his al-Musannaf. This report is the evidence for the juristic ruling that when a woman leads a congregation of women, she stands in the middle of the women following her rather than stepping forward ahead of the row.
