Answered by Shaykh Ilyas Patel
I want to find out whether I can lead a jamaat at home consisting of myself (Male) and my mother and sisters???
Yes, it is permissible to lead the jamaat at home with your family members. If people cannot make it to a masjid (such as if it is very far, or because of work timings), they should pray in jamaat with others to get the reward.
In Raddu’l Muhtar , Allama Ibn Abidin says :
… it is offensive to lead the women in a house where there is no other man or mahram of his (such as a sister or wife)…. If there is another man or mahran, or if he leads them in a masjid, then it is not offensive.
(Ibn Abidin, Radd al-Muhtar, 1.529)
And Allah knows best.
