Narrated Ibn `Abbas: When the Verse:-- If there are twenty steadfast amongst you, they will overcome two hundred. (8.65) was revealed, then it became obligatory for the Muslims that one (Muslim) should not flee from ten (non-Muslims). Sufyan (the sub-narrator) once said, Twenty (Muslims) should not flee before two hundred (non Muslims). Then there was revealed: 'But now Allah has lightened your (task)..' (8.66) So it became obligatory that one-hundred (Muslims) should not flee before two hundred (nonmuslims). (Once Sufyan said extra, The Verse: 'Urge the believers to the fight. If there are twenty steadfast amongst you (Muslims) ..' was revealed.) Sufyan said, Ibn Shabrama said, I see that this order is applicable to the obligation of enjoining good and forbidding evil.
