Al-Asma-ul-Husna ( اَلاسْمَاءُ الْحُسناى ) The 99 Most Beautiful Names and Attributes of Allah(سبحانه و تعالى) the Almighty
He is Allah, the Creator, the Inventor, the Fashioner; to Him belong the best names. Whatever is in the heavens and earth is exalting Him. And He is the Exalted in Might, the Wise. Surat Al-Hashr 59:24
And to Allah belong the best names, so invoke Him by them. Surat Al-A’raf 7:180
Allah – there is no deity except Him. To Him belong the best names. Surat Taha 20:8
Narrated Abu Huraira: Prophet Muhammad (صلى الله عليه و سلم) said, “Allah(سبحانه و تعالى) has ninety-nine names, i.e. one-hundred minus one, and whoever knows them will go to Paradise.” - Sahih Al-Bukhari – Book 50 Hadith 894
Abu Huraira reported Prophet Muhammad (صلى الله عليه و سلم) as saying: Verily, there are ninety-nine names for Allah(سبحانه و تعالى), i.e. hundred excepting one. He who enumerates them would get into Paradise. And on the authority of Abu Huraira who reported it from Prophet Muhammad (صلى الله عليه و سلم) that he said: “He is Odd (one) and loves odd number.” - Sahih Muslim – Book 35 Hadith 6476
It is not possible to perfectly translate the names and attributes of Allah(سبحانه و تعالى) from their original Arabic into English. However, here are some fairly close definitions.
