Daily prayers are the best medium through which one can Seek the nearness to Allah. Hajj is Jihad (Holy War) for every weak person. For everything that you own there is Zakat, and Zakat of your body is fasting. The Jihad of a woman is to afford pleasant company to her husband.
Mola Ali (a.s) Ibn e Abu Talib (a.s)
