;
In the Subjection of the Birds in the Sky there is a Sign

Then Allah tells His servants to look at the birds held (flying) in the sky, between heaven and earth, and how He has caused them to fly with their wings in the sky. They are held up only by Him, it is He Who gave them the strength to do that, subjecting the air to carry them and support them. As Allah says in Surat Al-Mulk:

﴿ أَوَلَمۡ يَرَوۡاْ إِلَى ٱلطَّيۡرِ فَوۡقَهُمۡ صَـٰٓفَّـٰتٍ۬ وَيَقۡبِضۡنَ‌ۚ مَا يُمۡسِكُهُنَّ إِلَّا ٱلرَّحۡمَـٰنُ‌ۚ إِنَّهُ ۥ بِكُلِّ شَىۡءِۭ بَصِيرٌ

(Do they not see the birds above them, spreading their wings out and folding them in None holds them up except the Most Gracious (Allah). Verily, He is the All-Seer of everything.) (67:19) And here Allah says:

﴿ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ۬ لِّقَوۡمٍ۬ يُؤۡمِنُونَ

(Verily, in this are clear signs for people who believe.)

﴿ وَٱللَّهُ جَعَلَ لَكُم مِّنۢ بُيُوتِڪُمۡ سَكَنً۬ا وَجَعَلَ لَكُم مِّن جُلُودِ ٱلۡأَنۡعَـٰمِ بُيُوتً۬ا تَسۡتَخِفُّونَهَا يَوۡمَ ظَعۡنِكُمۡ وَيَوۡمَ إِقَامَتِڪُمۡ‌ۙ وَمِنۡ أَصۡوَافِهَا وَأَوۡبَارِهَا وَأَشۡعَارِهَآ أَثَـٰثً۬ا وَمَتَـٰعًا إِلَىٰ حِينٍ۬ وَٱللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَـٰلاً۬ وَجَعَلَ لَكُم مِّنَ ٱلۡجِبَالِ أَڪۡنَـٰنً۬ا وَجَعَلَ لَكُمۡ سَرَٲبِيلَ تَقِيڪُمُ ٱلۡحَرَّ وَسَرَٲبِيلَ تَقِيكُم بَأۡسَڪُمۡ‌ۚ كَذَٲلِكَ يُتِمُّ نِعۡمَتَهُ ۥ عَلَيۡڪُمۡ لَعَلَّكُمۡ تُسۡلِمُونَ
﴿ فَإِن تَوَلَّوۡاْ فَإِنَّمَا عَلَيۡكَ ٱلۡبَلَـٰغُ ٱلۡمُبِينُ
﴿ يَعۡرِفُونَ نِعۡمَتَ ٱللَّهِ ثُمَّ يُنڪِرُونَہَا وَأَڪۡثَرُهُمُ ٱلۡكَـٰفِرُونَ

(80. And Allah had made your homes a place of rest for you, and made dwellings for you out of the hides of the cattle which you find so light when you travel and when you camp; and furnishings and articles of convenience out of their wool, fur, and hair - comfort for a while.) (81. And Allah has made shade for you out of that which He has created, and He has made places of refuge in the mountains for you, and He has made garments for you to protect you from the heat, and coats of mail to protect you from your violence. Thus does He perfect His favor for you, that you may submit yourselves to His will.) (82. Then, if they turn away, your duty (O Muhammad) is only to convey (the Message) in a clear way.) (83. They recognize the grace of Allah, yet they deny it (by worshipping others besides Allah) and most of them are disbelievers.)

Homes, Furnishings and Clothing are also Blessings from Allah

Allah mentions His great blessings for His servant in that He has given them homes to dwell in and protect themselves with, in which they find all kinds of benefits. He has also given them homes from the hides of cattle, i.e., leather, which are light and easy to carry on journeys and can be erected wherever they stop, whether they are traveling or are settled. Thus Allah says:

﴿ تَسۡتَخِفُّونَهَا يَوۡمَ ظَعۡنِكُمۡ وَيَوۡمَ إِقَامَتِڪُمۡ‌ۙ

(which you find so light when you travel and when you camp;)

﴿ وَمِنۡ أَصۡوَافِهَا وَأَوۡبَارِهَا وَأَشۡعَارِهَآ

(out of their wool, fur and hair) refers to sheep, camels and goats respectively.

﴿ أَثَـٰثً۬ا

(furnishings) meaning what you take from them, i.e., wealth. It was also said that it means articles of convenience, or clothing. The correct view is more general in meaning than this; it means that you make carpets, clothing and other things from their wool, hair etc., which you use as wealth and for trade. Ibn `Abbas said: `Al-Athath means articles of convenience and comfort.'' This was also the view of Mujahid, `Ikrimah, Sa`id bin Jubayr, Al-Hasan, `Atiyah Al-`Awfi, `Ata' Al-Khurasani, Ad-Dahhak and Qatadah. The phrase,

﴿ إِلَىٰ حِينٍ۬

(for a while) means, until the appointed time.

Shade, Places of Refuge in the Mountains, Garments and Coats of Mail are also Blessings from Allah
﴿ وَٱللَّهُ جَعَلَ لَكُم مِّمَّا خَلَقَ ظِلَـٰلاً۬

(And Allah has made shade for you out of that which He has created,) Qatadah said: "This means trees.''

﴿ وَجَعَلَ لَكُم مِّنَ ٱلۡجِبَالِ أَڪۡنَـٰنً۬ا

(and He has made places of refuge in the mountains for you,) meaning fortresses and strongholds.

﴿ وَجَعَلَ لَكُمۡ سَرَٲبِيلَ تَقِيڪُمُ ٱلۡحَرَّ

(and He has made garments for you to protect you from the heat,) meaning clothing of cotton, linen and wool.

﴿ وَسَرَٲبِيلَ تَقِيكُم بَأۡسَڪُمۡ‌ۚ

(and coats of mail to protect you from your violence.) such as shields made of layers of sheet iron, coats of mail and so on.

﴿ كَذَٲلِكَ يُتِمُّ نِعۡمَتَهُ ۥ عَلَيۡڪُمۡ

(Thus does He perfect His favor for you,) meaning, thus He gives you what you need to go about your business, so that this will help you to worship and obey Him.

﴿ لَعَلَّكُمۡ تُسۡلِمُونَ

(that you may submit yourselves to His will). This is interpreted by the majority to mean submitting to Allah or becoming Muslim.

All the Messenger has to do is convey the Message
﴿ فَإِن تَوَلَّوۡاْ

(Then, if they turn away,) meaning, after this declaration and reminder, do not worry about them.

﴿ فَإِنَّمَا عَلَيۡكَ ٱلۡبَلَـٰغُ ٱلۡمُبِينُ

(your duty (O Muhammad) is only to convey (the Message) in a clear way), and you have delivered the Message to them.

﴿ يَعۡرِفُونَ نِعۡمَتَ ٱللَّهِ ثُمَّ يُنڪِرُونَہَا

(They recognize the grace of Allah, yet they deny it) meaning they know that Allah is the One Who grants these blessings to them, and that He is Bountiful towards them, but they still deny this by worshipping others besides Him and thinking that their help and provisions come from others besides Him.

﴿ وَأَڪۡثَرُهُمُ ٱلۡكَـٰفِرُونَ

(and most of them are disbelievers.)

﴿ وَيَوۡمَ نَبۡعَثُ مِن كُلِّ أُمَّةٍ۬ شَهِيدً۬ا ثُمَّ لَا يُؤۡذَنُ لِلَّذِينَ ڪَفَرُواْ وَلَا هُمۡ يُسۡتَعۡتَبُونَ
﴿ وَإِذَا رَءَا ٱلَّذِينَ ظَلَمُواْ ٱلۡعَذَابَ فَلَا يُخَفَّفُ عَنۡہُمۡ وَلَا هُمۡ يُنظَرُونَ وَإِذَا رَءَا ٱلَّذِينَ أَشۡرَكُواْ شُرَڪَآءَهُمۡ قَالُواْ رَبَّنَا هَـٰٓؤُلَآءِ شُرَڪَآؤُنَا ٱلَّذِينَ كُنَّا نَدۡعُواْ مِن دُونِكَ‌ۖ فَأَلۡقَوۡاْ إِلَيۡهِمُ ٱلۡقَوۡلَ إِنَّكُمۡ لَڪَـٰذِبُونَ وَأَلۡقَوۡاْ إِلَى ٱللَّهِ يَوۡمَٮِٕذٍ ٱلسَّلَمَ‌ۖ وَضَلَّ عَنۡهُم مَّا كَانُواْ يَفۡتَرُونَ
﴿ ٱلَّذِينَ كَفَرُواْ وَصَدُّواْ عَن سَبِيلِ ٱللَّهِ زِدۡنَـٰهُمۡ عَذَابً۬ا فَوۡقَ ٱلۡعَذَابِ بِمَا ڪَانُواْ يُفۡسِدُونَ

(84. And on the Day when We resurrect a witness from each nation, then those who disbelieve will not be given leave, nor will they be allowed (to return to the world) to repent and ask for Allah's forgiveness.) 85. And once those who did wrong see the torment, it will not decrease for them, nor will they be given respite.) (86. And when those who associated partners with Allah see their partners, they will say: "Our Lord! These are our partners whom we used to call upon besides you.'' But they will throw back their statement at them (saying): "You indeed are liars!'') (87. And they will offer (their full) submission to Allah on that Day, and what they falsely invented will wander away from them.) (88. Those who disbelieved and tried to obstruct the path of Allah, for them We will add torment on top of the torment because of the corruption they spread.)
