Sahih Muslim | Book 25 | Hadith Number 5331
Narrated by Jabir b. 'Abdullah
Jabir b. 'Abdullah reported: Allah's Messenger (may peace be upon him) decided to forbid (his followers) to name persons as Ya'la (Elevated), Baraka (Blessing), Aflah (Successful), Yasar and Nafi', but I saw that he kept silent after that and he did not say anything until Allah's Messenger (may peace be upon him) died. And he did not forbid (his followers to do this), then 'Umar decided to prohibit (people) from giving these names, but later on gave up the idea.
