Al-Tawḥīd > He, the Mighty and High, in not Recognized, Except by Himself.
Hadith #2

2 - حدثنا محمد بن الحسن بن أحمد بن الوليد رحمه الله، قال: حدثنا محمد بن الحسن الصفار، عن أحمد بن محمد بن خالد، عن بعض أصحابنا، عن علي بن عقبة بن قيس ابن سمعان بن أبي ربيحة مولى رسول الله صلى الله عليه وآله رفعه، قال: سئل أمير المؤمنين عليه السلام بم عرفت ربك؟ فقال: بما عرفني نفسه، قيل: وكيف عرفك نفسه؟ فقال: لا تشبهه صورة، ولا يحس بالحواس، ولا يقاس بالناس، قريب في بعده، بعيد في قربه، فوق كل شئ ولا يقال: شئ فوقه، أمام كل شئ ولا يقال: له أمام، داخل في الأشياء لا كشئ في شئ داخل، وخارج من الأشياء لا كشئ من شئ خارج، سبحان من هو هكذا ولا هكذا غيره، ولكل شئ ومبتدء.

2. Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid (RA) said: Muhammad ibn al-Hasan alSaffar said, on the authority of Ahmad ibn Muhammad ibn Khalid, on the authority of some of our scholars, on the authority of `Ali ibn `Uqbah ibn Qays ibn Sam`an ibn Abu Rabihah, the freed slave of the Messenger of Allah (SA), who hurried the transmission that The Commander of the Faithful was questioned, “With what do you recognize your Lord?” He (AS) answered, “With what He introduced Himself.” It was said: “How did He introduce Himself to you?” He (AS) replied, No image resembles Him. He is neither perceived by the senses, nor compared with the people. He is Near in His Farness, and Far in His Nearness. He is Above all Things. It cannot be said that “something is above Him,” as He is in front of everything. It cannot be said that “He has a front,” since He is Inside Everything, but without being contained. He is Outside of Everything, but without being absent from anything. Glory be Him! There is nothing like unto Him. He is the Originator of All Things.
