Which do you think would be the hardest pillar to fulfill.
1.Shahadah - Declaration of faith
2.Salah - Prayer [5 prayers a day]
3.Zakah - Charity [Giving 2.5% to a charity]
4.Sawn - Fasting
5.Hajj - Pilgrimage.
For me it would be Hajj cause I don't like traveling.
Also in todays society and where I live , Salah would be pretty hard to follow as well.
