Say: "O My servants who believe, have Taqwa of your Lord. Good is for those who do good in this world, and Allah's earth is spacious! Only those who are patient shall receive their reward in full, without reckoning. (10)Say: "Verily, I am commanded to worship Allah, making religion sincerely for Him.

The Command for Taqwa, Emigration and to worship Him alone with all Sincerity

Allah commands His believing servants to remain steadfast in their obedience and have Taqwa of Him.

قُلْ يَا عِبَادِ الَّذِينَ آمَنُوا اتَّقُوا رَبَّكُمْ ۚ لِلَّذِينَ أَحْسَنُوا فِي هَٰذِهِ الدُّنْيَا حَسَنَةٌ ۗ

(Say: "O My servants who believe, have Taqwa of your Lord. Good is for those who do good in this world...") means, the one who does good deeds in this world, will have a good (reward) in this world and in the Hereafter.

وَأَرْضُ اللَّهِ وَاسِعَةٌ ۗ

(and Allah's earth is spacious!) Mujahid said, "So emigrate through it and strive hard and keep away from idols."

إِنَّمَا يُوَفَّى الصَّابِرُونَ أَجْرَهُمْ بِغَيْرِ حِسَابٍ

(Only those who are patient shall receive their reward in full, without reckoning.) Al-'Awza'i said, "Their reward will not be weighed or measured; they will be given an immense reward." As-Suddi said:

إِنَّمَا يُوَفَّى الصَّابِرُونَ أَجْرَهُمْ بِغَيْرِ حِسَابٍ

(Only those who are patient shall receive their reward in full, without reckoning.) means, "In Paradise."

قُلْ إِنِّي أُمِرْتُ أَنْ أَعْبُدَ اللَّهَ مُخْلِصًا لَهُ الدِّينَ

(Say: "Verily, I am commanded to worship Allah, making religion sincerely for Him...") means, 'I am commanded to worship Allah alone in all sincerity, with no partner or associate.'

وَأُمِرْتُ لِأَنْ أَكُونَ أَوَّلَ الْمُسْلِمِينَ

(And I am commanded (this) in order that I may be the first of the Muslims.)
