Sahl bin Sa'd As-Sa'idi:
That the Messenger of Allah (ﷺ) said: "Going out in the morning in the cause of Allah is better that the world and what is in it. And the place (the size) of a whip in Paradise is better than the world and what is in it."
[Abu 'Eisa said:] There are narrations on this topic from Abu Hurairah, Ibn 'Abbas, Abu Ayyub, and Anas.
This Hadith is Hasan Sahih.
