ALLAH, The ONE and ONLY
"Say: He is ALLAH, the One and Only;"
[Quran - 112:1 - Abdullah Yusuf Ali]
The Prophet (pbuh) has said:
“Followers of the Qur’an, observe (devotions) an odd number of times, for Allah is Indivisible and loves that which is indivisible.” [Sunan al-Tirmidhī (453), Sunan Abī Dāwūd (1416), Sunan al-Nasā’ī (1675), and Sunan Ibn Mājah (1169)]
