Then Allah says:

﴿وَتَوَكَّلْ عَلَى الْحَىِّ الَّذِى لاَ يَمُوتُ﴾

(And put your trust in the Ever Living One Who dies not,) meaning, in all your affairs, put your trust in Allah, the Ever-Living Who never dies, the One Who

﴿الاٌّوَّلُ وَالاٌّخِرُ وَالظَّـهِرُ وَالْبَـطِنُ وَهُوَ بِكُلِّ شَىْءٍ عَلِيمٌ﴾

(is the First and the Last, the Most High and the Most Near. And He is the All-Knower of everything) (57:3). The Eternal, Ever-Lasting, Ever-Living, Self-Sufficient One, the Lord and Sovereign of all things, the One to Whom you should always turn. Allah is the One in Whom you should put your trust and to Whom you should turn for refuge, He will be sufficient for you and will be your helper and supporter, and will cause you to prevail. As Allah says:

﴿يَـأَيُّهَا الرَّسُولُ بَلِّغْ مَآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ وَاللَّهُ يَعْصِمُكَ مِنَ النَّاسِ﴾

(O Messenger! Proclaim which has been sent down to you from your Lord. And if you do not, then you have not conveyed His Message. Allah will protect you from mankind) (5:67).

﴿وَسَبِّحْ بِحَمْدِهِ﴾

(and glorify His praises,) means, combine praising Him with glorifying Him. Hence the Messenger of Allah used to say:

«سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِك»

(Glory be to You, O Allah, and with Your praise.) So the Ayah means: be sincere in worshipping Him and putting your trust in Him. This is like the Ayat:

﴿رَّبُّ الْمَشْرِقِ وَالْمَغْرِبِ لاَ إِلَـهَ إِلاَّ هُوَ فَاتَّخِذْهُ وَكِيلاً ﴾

(The Lord of the east and the west; there is no God but He. So take Him as a Trustee.) (73:9)

﴿فَاعْبُدْهُ وَتَوَكَّلْ عَلَيْهِ﴾

(So worship Him and put your trust in Him) (11:123).

﴿قُلْ هُوَ الرَّحْمَـنُ ءَامَنَّا بِهِ وَعَلَيْهِ تَوَكَّلْنَا﴾

(Say: "He is the Most Gracious, in Him we believe, and in Him we put our trust.'') (67:29)

﴿وَكَفَى بِهِ بِذُنُوبِ عِبَادِهِ خَبِيراً﴾

(and sufficient is He as the All-Knower of the sins of His servants) means, by His perfect knowledge nothing is hidden from Him nor can anything be hidden from Him, not even a speck of dust's weight.

﴿الَّذِى خَلَقَ السَّمَـوَتِ وَالاٌّرْضَ﴾

(Who created the heavens and the earth...) means, He is the Ever-Living Who never dies, He is the Creator, Sustainer and Sovereign of all things, Who by His might and power created the seven heavens with their vast height and width, and the seven earths with their great depths and density.

﴿فِي سِتَّةِ أَيَّامٍ ثُمَّ اسْتَوَى عَلَى الْعَرْشِ﴾

(in six Days. Then He rose over the Throne.) means, He is running all affairs and He decrees according to the truth, and He is the best of those who decide.

﴿ثُمَّ اسْتَوَى عَلَى الْعَرْشِ الرَّحْمَـنُ فَاسْأَلْ بِهِ خَبِيراً﴾

(Then He rose over (Istawa) the Throne. The Most Gracious! Ask Him, as He is the All-Knower.) meaning, find out about Him from one who knows most about Him, and follow him and take him as your example. It is known that there is no one who knows more about Allah than His servant and Messenger Muhammad , the absolute leader of the sons of Adam in this world and the Hereafter, who does not speak of his own desire, but conveys revelation revealed to him. What he says is true, and he is the leader whose decision counts; when there is a dispute, people are obliged to refer to him, and whatever is in accordance with his words and deeds is right, and whatever goes against them should be rejected no matter who says or does it. Allah says:

﴿فَإِن تَنَازَعْتُمْ فِى شَىْءٍ﴾

((And) if you differ in anything among yourselves...) (4:59).

﴿وَمَا اخْتَلَفْتُمْ فِيهِ مِن شَىْءٍ فَحُكْمُهُ إِلَى اللَّهِ﴾

(And in whatsoever you differ, the decision thereof is with Allah) (42:10).

﴿وَتَمَّتْ كَلِمَةُ رَبِّكَ صِدْقاً وَعَدْلاً﴾

(And the Word of your Lord has been fulfilled in truth and in justice) (6: 115). meaning, He has spoken the truth and is fair and just in His commands and prohibitions. Allah says here:

﴿فَاسْأَلْ بِهِ خَبِيراً﴾

(Ask Him, as He is Al-Knower.)
