It is narrated from Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: No deceiver, no miser, no one who reminds others of his favors, and no ill-mannered person will enter Paradise. And the first person to knock at the door of Paradise will be a slave, provided that he obeys Allah and also obeys his master.
