Abdur-Rahman bin Yazid narrated that:
Thawban said: “The Messenger of Allah said: 'Who will commit himself to ** one thing**, I will guarantee him paradise?' I said: 'I will.' He said: '**Do not ask people for anything**.'
So Thawban would drop his whip while he was on his mount, and he would not say to anyone: ‘Get that for me’ rather he would dismount and grab it.”
[Sunan Ibn Majah Hadith No. 1837]
