Respected Sister, Salam o Rahmat,
I find 2:255 AYAT-AL-KURSI very soothing.
2:255 (These directions, tidings and warnings come from God) the One True God, there is no god but He, the Living, the Originator of life, the Self-Subsisting Lord of all creation. Neither slumber, nor sleep overtakes Him. All that exists in the highs and the lows, in the heavens and earth, belongs to Him alone. Who can intercede in His Court except by His Leave, and then, only in accordance with His Laws? He knows what lies open before humans and what is hidden from them. His knowledge transcends time and space. No one can encompass a trace of His knowledge but through His Laws. The Throne of His Supreme Control extends over the highs and the lows. No fatigue touches Him as He benevolently guards His Dominion and creation. He is the Glorious, the Supreme. [This verse, commonly known as Ayat-al-Kursi (Verse of the Throne), is greatly revered by many Muslims for its grandeur and eloquence. Shafa’ah = Commonly translated as Intercession = To stand up as witness = Give evidence = Vindicate the truth. 2:48, 2:123, 4:85, 6:51, 6:70, 10:3, 19:87, 20:109, 21:28, 32:4, 34:23, 39:44, 43:86, 74:48]
Also, Surah 112 IKHLAS
Surah 112. Al-Ikhlas – The Pure Monotheism
Author’s note: This a very brief Surah that very forcefully and clearly expounds strict Monotheism, nothing confusing about it such as Trinity, Dualism or any shade of Polytheism.
With the Glorious Name of God, the Instant and Sustaining Source of all Mercy and Kindness
112:1 Say, "He is God, the One and Unique! [He is Unique in His Essence and Attributes and He alone is the Sovereign Law-Giver in the Universe. ‘Wahid’ = One. ‘Al-Ahad’ = The Unique]
112:2 God is Absolutely Independent. [Samad = Absolute, Eternal, Unique, Absolutely Independent Lord, Perfect, the Uncaused Cause of all that exists]
112:3 He begets not, nor is He begotten.
112:4 And there is absolutely none like Him."
Please do not forget us.
