What is the lowest level of knowledge?

Hawzah News Agency - Muhammad ibn al-Hasan reported from Abdullah ibn al-Hasan al-Alawi, and Ali ibn Ibrahim reported from al-Mukhtar ibn Muhammad ibn al-Mukhtar al-Hamdani, all from al-Fath ibn Yazid, from Abu al-Hasan (Imam al-Ridha) , who said:

سَأَلْتُهُ عَنْ أَدْنَى الْمَعْرِفَةِ فَقَالَ الاقْرَارُ بِأَنَّهُ لا إِلَهَ غَيْرُهُ وَلا شِبْهَ لَهُ وَلا نَظِيرَ وَأَنَّهُ قَدِيمٌ مُثْبَتٌ مَوْجُودٌ غَيْرُ فَقِيدٍ وَأَنَّهُ لَيْسَ كَمِثْلِهِ شَيْ‏ءٌ.

"I asked him about the lowest level of knowledge. He said: 'The acknowledgment that there is no deity other than Him, and that there is no similarity or counterpart to Him, and that He is Eternal, Affirmed, Existing, not lacking anything, and that there is nothing like Him.'"
