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.
