The Heights - 7:143
"When Moses came to us at the appointed time and his Lord spoke to him, he said, "My Lord, appear to me and let me look at you. "You cannot see me. But look at this mountain; if it stands still, then you will see me."When his Lord appeared to the mountain, He shattered it, and Moses fell unconscious. When he came to his senses, he said, "You are great, to You I turn, and I am the foremost of the believers."
It is a favor from our Lord that He spoke to Moses.
The Cow/2:253
And We favored some of those messengers more than others, for example, with some Allah spoke, and with some He raised them in degrees. We gave clear proofs to Jesus son of Mary and supported him with the Holy Spirit. Had Allah willed, those who came after them would not have quarrelled with one another after clear proofs had come to them. But they differed. Some believed and some disbelieved. Had Allah willed, they would not have fought one another. But Allah does what He wills.
The Women/4:164
And to the messengers We told you of before, and to the messengers We did not tell you of... And Allah had spoken to Moses with words.
