Thauban (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "He who guarantees me that he will not beg anything from anyone, I will guarantee him (to enter) Jannah." I said, "I give you the guarantee." Then Thauban (May Allah be pleased with him) never begged anything from anyone.[Abu Dawud].
