Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: By Allah, besides whom there is no god, the best prayer a woman offers is the one she offers in her house; but prayer offered in al-Masjid al-Haram or the Prophet's Mosque is better in any case, except for an old woman who prays in her (worn) footwear.
