Uluw of Allah from the words of imam

Salam alaikum.

Narrated by Kulayni in “Kafi” 1/126:

4 – علي بن محمد، عن سهل بن زياد، عن محمد بن عيسى قال: كتبت إلى أبي الحسن علي بن محمد (عليهما السلام): جعلني الله فداك يا سيدي قد روي لنا: أن الله في موضع دون موضع على العرش استوى، وأنه ينزل كل ليلة في النصف الاخير من الليل إلى السماء الدنيا، وروي: أنه ينزل عشية عرفة ثم يرجع إلى موضعه، فقال بعض مواليك في ذلك: إذا كان في موضع دون موضع، فقد يلاقيه الهواء ويتكنف عليه والهواء جسم رقيق يتكنف على كل شئ بقدره، فكيف يتكنف عليه جل ثناؤه على هذا المثال؟ فوقع (عليه السلام): علم ذلك عنده  وهو المقدر له بما هو أحسن تقديرا واعلم أنه إذا كان في السماء الدنيا فهو كما هو على العرش، والاشياء كلها له سواء علما وقدرة وملكا وإحاطة.

وعنه، عن محمد بن جعفر الكوفي، عن محمد بن عيسى مثله

Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Muhammad ibn ‘Isa who has said
the following.
“I wrote to Imam abu al-Hassan, Ali ibn Muhammad (a.s.) to clarify a question. May Allah take my soul in your service, O my master, it is narrated to us that Allah is in one place and not in another place on ‘Arsh, (the Throne) resting. He comes down to the sky above the earth every night during the last half of the night. It is narrated that He comes down at the ninth
evening of the month of Dhul Hajj and then He returns back to His place. Certain individuals among your friends have said that if He would be found in certain places and not in otherplaces the air must have come in contact with Him and would surround Him because air is a thin form of body that surrounds everything proportionate to its size. How then the air would surround Allah, the Most Holy and the Most High, According to this assumption? The Imam replied in writing, “He has the knowledge of this. He is the best One in having the true measurements of all things. You must, However, note that His being in the sky over the earth is just as He on the Throne. All things to Him are the same in the matters of His knowledge and power, domination and control.”
Muhammad ibn Ja‘far al-Kufi has narrated from Muhammad ibn ’Isa a similar Hadith
