Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated Ibn Mas`ud:
The Prophet (ﷺ) said, "Soon others will be preferred to you, and there will be things which you will not like." The companions of the Prophet (ﷺ) asked, "O Allah's Messenger (ﷺ)! What do you order us to do (in this case)? " He said, "(I order you) to give the rights that are on you and to ask your rights from Allah."
