Translation
Narrated Ibn 'Abbas: That the Prophet (ﷺ) said: "Shall I not inform you of the best of the people ? A man who takes hold of the reins of his horse in Allah's cause. Shall I not inform you of the one who comes after him ? The man who secludes himself from the people with a small group of sheep of his, thereby fulfilling Allah's right. Shall I not inform you about the worst of the people ? A man who is asked by (the Name of) Allah, but not given by Him." [Abu 'Eisa said:] This Hadith is Hasan Gharib from this route. This Hadith has been reported through other routes from Ibn 'Abbas, from the Prophet (ﷺ)
