4a]
Narrated by Abu Dawood, 591; classed as hasan by Shaykh al-Albaani in
Irwa'al-Ghaleel, 493.
And it was narrated from 'Aa'ishah that she would give the call to
prayer andlead other women in prayer, standing in the middle of the
row.
And 'Aa'ishah led women in obligatory prayers, standing in the midst of them.
And it was narrated that Hujayrah bint Haseen said: Umm Salamaah led
us in prayer standing in the midst of the women.
And it was narrated from Umm al-Hasan that she saw Umm Salamah, the
wife of the Prophet (peace and blessings of Allaah be upon him),
leading women in prayer, standing with them in their row.
Shaykh al-Albaani (may Allaah have mercy on him) said, after narrating
these reports:
In conclusion, these reports are sound and may be acted upon,
especially since they confirm the general meaning of the words of the
Prophet (peace and blessings of Allaah be upon him): "Women are the
twin halves of men…"
Sifat Salaat al-Nabi (peace and blessings of Allaah be upon him), p. 153-155.
Ibn Qudaamah (may Allaah have mercy on him) said:
She should recite out loudin prayers where it is required to recite
out loud, but if there are any men present, she should not recite out
loud, unlessthey are her mahrams, in which case she may do so.
