Praise be to Allaah.
We put this question to Shaykh Muhammad ibn
Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows:
It is better for them to pray in jamaa’ah,
if possible, but the reward of twenty-seven times more applies only
to men, because praying in jamaa’ah is obligatory for them.
“The correct view is that for women
to pray in jamaa’ah, and for a woman to lead other women in prayer,
are things that are permitted in Islam and indeed are mustahabb for
them. The evidence (daleel) for that is the hadeeth of Um Waraqah that
we have referred to above, in which it states that the Prophet
(peace and blessings of Allaah be upon him) gave her permission to lead
the (female) members of her household in prayer… It is also confirmed
by the fact that some of the Mothers of the Believers led other women
in prayer. It was reported from Laytah al-Hanafiyyah (from the tribe
of Banu Haneefah) that ‘Aa’ishah the Mother of the Believers led them
in the obligatory prayer. And it was narrated from Tameemah bint Saleemah
that ‘Aa’ishah the Mother of the Believers (may Allaah be pleased with
her) led women in Maghrib prayer, and that she stood in the middle of
them and recited Qur’aan aloud. It was also narrated that Um Salamah
the Mother of the Believers (may Allaah be pleased with her) used to
lead women in prayer in Ramadaan, and that she stood with them in the
row. And it was narrated that Ibn ‘Umar used to tell one of his slave
women to lead his womenfolk in prayer in Ramadaan.”
