The Messenger of Allah (sal Allahu alaihi wa sallam) said: “The most likeable Salat of a woman to Allah is the one which she offers in her house privately and in a dark place.” [Ibn Khuzaimah]
Praying in privacy secludes her from distractions and allows her to focus on her communication with Allah (subhana wa ta’ala). It is also easier for women not to have to leave their houses or walk through men. It may be burning hot or freezing cold outside but she does not have to brave the weather to get the same reward as men. She doesn’t have to drag small children along, nor leave them with baby-sitters with going back and forth from the Masjid as men are required to do.
The role Allah (subhana wa ta’ala) requires men to play in society is different. They have to handle the work outdoors and work to provide for themselves as well as their families. The role Allah (subhana wa ta’ala) has given to women is to make the home a comfortable and welcoming place where her children can grow up to love Allah, His Prophet and Islam, and live peacefully.
This Hadith is a special blessing for women given the nature of their responsibilities at home and with (especially small) children. All praise is due to Allah the Most Merciful that He rewards women even more to do what is more convenient for them and their households.
