In the surah 17, Al Isra, verse 110, we find, “Say (O Muhammad ), “Invoke Allah or invoke the Most Gracious (Allah), by whatever name you invoke Him (it is the same), for to Him belong the Best Names. And offer your Salat (prayer) neither aloud nor in a low voice, but follow a way between.”
Here is a hadit from Bukhari explaining about the 99 Asma-e-Husna:
Allah has ninety-nine Names, i.e., one hundred minus one, and whoever believes in their meanings and acts accordingly, will enter Paradise; and Allah is Witr (one) and loves ‘the Witr’ (i.e., odd numbers).
These 99 names define Tawheed, which is the foundation of Islamic belief. It is easier to memorize and understand the meaning of each one of this Asma-e-Husna at an early age. Therefore, EAST has made these 99 names a part of class five Islamiat book: The Journey of Islam (Islam ka Safar). This poster is a visual aid to support the book. You can display this poster in home and school so children can learn these names easily.
