As-Salaam alaikum,

"I hear and I see". The meaning of Allah's words [Subhanahu Wa Ta'ala ]: "I hear", means 'I hear what has occurred between you two [Prophets Musa and Harun, alaihimus-salaam ] and Pharaoh, therefore I will make you 2 understand how to debate with him'. Thus no hidden thing is concealed from Allah Ta'ala, Blessed be Him, the Lord of the worlds.

This Ayat proves that deafness and blindness are both impossible to Him, Jallah Wa 'alaa.... He is All-Hearing and All-Seeing. Infact, notable 'Ulama in the religion of Islam have taught us that the special qualities of the 1st Name in this Ayat: as-Samee'u is its effectiveness in the answering of supplications, for whoever recites it by saying: 'Yaa Samee'u on Thursday after the forenoon prayer (ad-duha) 500 times will have his/her supplication answered.

And the special qualities of the 2nd Name: al-Baseeru is its effectiveness in bringing about success in one's affairs, for whoever recites it by saying: 'Ya Baseeru before the Friday (Jumma'a) prayer 100 times, Allah will open for him his inner vision and make him successful in Righteous words and actions.
