Praise be to Allah.
A woman who is menstruating may do all acts of worship apart from praying, fasting, circumambulating the Ka’bah and doing i’tikaaf in the mosque.
It was narrated that the Prophet (peace and blessings of Allah be upon him) used to stay up at night during the last ten nights of Ramadan.
Al-Bukhaari (2401) and Muslim (1174) narrated that ‘Aa’ishah (may Allah be pleased with her) said: “When the last ten nights of Ramadaan came, the Prophet (peace and blessings of Allah be upon him) would refrain from marital relations, stay up at night and wake his family up.”
Staying up at night is not only for prayer, rather it includes all kinds of acts of worship. This is how the scholars interpreted it.
Al-Haafiz said: “Staying up at night” means staying up to do acts of worship.
Al-Nawawi said: spending the night staying up to pray etc.
He said in ‘Awn al-Ma’bood: i.e., in prayer, dhikr and reciting the Qur’aan.
Praying qiyaam is the best act of worship that a person can do on Laylat al-Qadr. Hence the Prophet (peace and blessings of Allah be upon him) said: “Whoever spends the night of Laylat al-Qadr in prayer out of faith and in hope of reward, his previous sins will be forgiven.”
(Narrated by al-Bukhaari, 1901; Muslim, 760).
Because the woman who is menstruating is not allowed to pray, she can spend the night in doing other acts of worship apart from prayer, such as:
1 – Dhikr – such as saying Subhaan-Allah, La ilaaha illa-Allaah, al-Hamdu Lillaah, etc. She can repeat the words “Subhaan-Allah wa’l-hamdu Lillaah, wa laa ilaaha ill-Allah, wa Allaahu akbar (Glory be to Allah, praise be to Allah, there is no god but Allah and Allah is Most Great)” and “Subhaan Allah wa bi hamdihi, subhaan Allah il-‘Azeem (Glory and praise be to Allah, glory be to Allah the Almighty)” etc.
2 – Istighfaar (praying for forgiveness), by repeating the phrase “Astaghfir-Allah (I ask Allah for forgiveness).”
3 – Du’aa’ (supplication) – she can pray to Allah and ask Him for what is good in this world and in the Hereafter, for du’aa’ is one of the best acts of worship.
The Prophet (peace and blessings of Allah be upon him) said, “Du’aa’ is ‘ibaadah (worship).”
(Narrated by al-Tirmidhi, 2895; classed as saheeh by al-Albaani in Saheeh al-Tirmidhi, 2370).
The woman who is menstruating can do these acts of worship and others on Laylat al-Qadr.
We ask Allah to help us to do that which He loves and which pleases Him.
May Allah accept our righteous deeds.
