وَلَقَدْ خَلَقْنَا الإِنسَانَ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُون وَالْجَآنَّ خَلَقْنَاهُ مِن قَبْلُ مِن نَّارِ السَّمُوم وَإِذْ قَالَ رَبُّكَ لِلْمَلاَئِكَةِ إِنِّي خَالِقٌ بَشَرًا مِّن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ
فَإِذَا سَوَّيْتُهُ وَنَفَخْتُ فِيهِ مِن رُّوحِي فَقَعُواْ لَهُ سَاجِدِينَ فَسَجَدَ الْمَلآئِكَةُ كُلُّهُمْ أَجْمَعُونَ إِلاَّ إِبْلِيسَ أَبَى أَن يَكُونَ مَعَ السَّاجِدِينَ قَالَ يَا إِبْلِيسُ مَا لَكَ أَلاَّ تَكُونَ مَعَ السَّاجِدِينَ قَالَ لَمْ أَكُن لِّأَسْجُدَ لِبَشَرٍ خَلَقْتَهُ مِن صَلْصَالٍ مِّنْ حَمَإٍ مَّسْنُونٍ قَالَ فَاخْرُجْ مِنْهَا فَإِنَّكَ رَجِيمٌ وَإِنَّ عَلَيْكَ اللَّعْنَةَ إِلَى يَوْمِ الدِّينِ قَالَ رَبِّ فَأَنظِرْنِي إِلَى يَوْمِ يُبْعَثُونَ قَالَ فَإِنَّكَ مِنَ الْمُنظَرِينَ إِلَى يَومِ الْوَقْتِ الْمَعْلُومِ قَالَ رَبِّ بِمَا أَغْوَيْتَنِي لأُزَيِّنَنَّ لَهُمْ فِي الأَرْضِ وَلأُغْوِيَنَّهُمْ أَجْمَعِينَ إِلاَّ عِبَادَكَ مِنْهُمُ الْمُخْلَصِينٍَِ

Verily We created man of potter's clay of black mud altered. And the jinn did We create aforetime of essential fire. 

And (remember) when thy Lord said unto the angels: Lo! I am creating a mortal out of potter's clay of black mud altered. So, when I have made him and have breathed into him of My spirit, do ye fall down, prostrating yourselves unto him.

So the angels fell prostrate, all of them together. Save Iblis. He refused to be among the prostrate. He said: O Iblis! What aileth thee that thou art not among the prostrate?  He said: Why should I prostrate myself unto a mortal whom Thou hast created out of potter's clay of black mud altered? 
He said: Then go thou forth from hence, for verily thou art outcast.  And lo! the curse shall be upon thee till the Day of Judgment.  He said: My Lord!Reprieve me till the day when they are raised. < He said: Then lo! Thou art of those reprieved; Till an appointed time.  He said: My Lord, Because Thou has sent me astray, I verily shall adorn the path of error for them in the earth, and shall mislead them every one. Save such of them as are Thy perfectly devoted slaves. [El Hijr-verses 26-40]

 Marmeduke Pickthal translation of the Quran

Allah says that verily He created Adam from clay made of black mud and that before the creation of Adam, He created the jinn from fire of a scorching wind. Allah told the angels that He was going to create man from clay made of black mud.
 He told the angels that after He fashioned Adam and breathed into him from His spirit that they had to bow down to Adam.  All of the angels bowed down to Adam.  However, Iblis refused to bow.  Allah asked Iblis why he refused to bow.  Iblis said that he would not bow down to a man that He (Allah) created from clay made of black mud.  Allah then expelled Iblis from Paradise and cursed him. 
Iblis asked Allah to grant him respite until the Day of Resurrection and Allah granted him respite.  Iblis then said that he would lead Adam’s descendants astray; all of them except Allah’s sincere servants.It is a known fact that the Arabic word for black mud is hama.  Also, the scholars say the following about the word hama in their tafsirs (explanation) of the Quran:  

• Explaining hama in the verses above, El Quortobi says in his tafsir of the Quran:

“Hama is black mud.” والحمأ: الطين الأسود 

 Explaining hama in the verses above, Jalal Eddine Mohamed Ahmed El-Mahalli and Jalal Eddine Abdel Rahman El-Sayouti say in their tafsir of the Quran called Tafsir El-Jalaalain:

وأما قوله "من حمإ مسنون" فإن الحمأ : جمع حمأة ، وهو الطين المتغير إلى السواد 

Explaining hama in the verses above, Mohamed ibn Ali El-Shawkaani says in his tafsir of the Quran called Fath El Qadir:

“Hama is black mud; either black mud that has been altered or black mud that hasn’t been altered.

والحمأ: الطين الأسود المتغير. أو الطين الأسود من غير تقييد بالمتغير

 “From hama” means from mud which

was altered and is black.

" من حمإ" طين تغير واسود من طول محاورة الماء 

Explaining hama in the verse above, El-Baghawi says in his tafsir:

“From hama” and hama is black mud.

من حمإ"، والحمأ: الطين الأسود"

       El-Baghawi also said: 

Adam was created from and let it sit until it became altered and

black and then He created Adam peace be upon him from it (the black, altered mud).”

• Ibn al-Qayyim said: 

• Explaining hama, which is also found in verse 86 of surat El-Kahf,  Ibn Kathir says in his tafsir:

" حمئة " أي كثيرة الحمأة وهي الطينة السوداء
