"Go forth, light and heavy, and strive hard in Allah's way with your wealth and your lives. This is better for you, if you know. Had it been a near gain and a short journey, they would certainly have followed thee, but the hard journey was too long for them. And they wilt swear by Allah: If we had been able, we would have gone forth with you. They cause their own souls to perish; and Allah knows that they are liars."
