Narrated Sahl bin Sa'd: That the Messenger of Allah (ﷺ) said: "(Ribat) Guarding the frontier for a day in the cause of Allah is better than the world and what is in it. And an afternoon the worshipper spends in the cause of Allah - or a morning - is better than the world and what is on it. And the space occupied by the whip of one of you in Paradise is better than the world and what is on it." This Hadith is Hasan Sahih
