Al-Ahad - Calligraphy Wall Art
Allah سُبْحَٰنَهُۥ وَتَعَٰلَىٰ is Al-Ahad (in Arabic: ٱلْأَحَد), He is incomparable, unequaled, and indivisible. Al-Ahad is the One who was, is, and will ever remain alone. No one can ever be equal to Him in the essence of all His beautiful attributes.
From the root hamza-ha-dal (أ ح د), which has the following classical Arabic connotations: to be one, to be the only one, one alone, sole, to unite, unify.
The name Al-Ahad appears in one place, and that is in Surah Ikhlas. قُلْ هُوَ ٱللَّهُ أَحَدٌ - "Say, “He is Allah, [who is] One," وَلَمْ يَكُن لَّهُۥ كُفُوًا أَحَدٌۢ - "Nor is there to Him any equivalent."
Sa'īd b. al-Musayyib reported in mursal form that the Prophet said, “If anyone recites ten times ‘Say, He is God, One’, a palace will be built for him in paradise because of it; if anyone recites twenty times two palaces will be built for him in paradise because of it; and if anyone recites it thirty times three palaces will be built for him in paradise because of it.” ‘Umar b. al-Khattāb said, “I swear by God, messenger of God, that we shall then produce many palaces for ourselves;” to which he replied, “God's abundant grace is even more comprehensive than that.” (Mishkat al-Masabih 2185).
Anas said: One of the Ansar used to lead the Ansar in Salat in the Quba' mosque and it was his habit to recite Qul Huwal-lahu Ahad whenever he wanted to recite something in Salat.
When he finished that Surah, he would recite another one with it. He followed the same procedure in each Rak'a. His companions discussed this with him and said, "You recite this Surah and do not consider it sufficient and then you recite another. So would you recite it alone or leave it and recite some other."
He said, "I will never leave it and if you want me to be your Imam on this condition then it is all right; otherwise I will leave you."
They knew that he was the best amongst them and they did not like someone else to lead them in Salat. When the Prophet ﷺ went to them as usual, they informed him about it.
The Prophet ﷺ addressed him and said, "O so-and-so, what forbids you from doing what your companions ask you to do? Why do you read this Surah particularly in every Rak'a ?" He repiled, "I love this Surah." The Prophet ﷺ said, "Your love for this Surah will make you enter Paradise." (Sahih al-Bukhari 774b).
Abu Darda reported Allah's Apostle ﷺ as saying: Is any one of you incapable of reciting a third of the Qur'an in a night? They (the Companions) asked: How could one recite a third of the Qur'an (in a night)? Upon this he (the Holy Prophet ﷺ) said: "'Say: He is Allah, One' (Qur'an 112) is equivalent to a third of the Qur'an." (Sahih Muslim 811a & Riyad as-Salihin 1010).
