Adh-Dhariyat 51:20

كَانُوا قَلِيلًا مِّنَ اللَّيْلِ مَا يَهْجَعُونَ

They used to sleep but little of the night,

وَبِالْأَسْحَارِ هُمْ يَسْتَغْفِرُونَ

And in the hours before dawn they would ask forgiveness,

وَفِي أَمْوَالِهِمْ حَقٌّ لِّلسَّائِلِ وَالْمَحْرُومِ

And from their properties was [given] the right of the [needy] petitioner and the deprived.

وَفِي أَنفُسِكُمْ ۚ أَفَلَا تُبْصِرُونَ

And in yourselves. Then will you not see?

وَفِي السَّمَاءِ رِزْقُكُمْ وَمَا تُوعَدُونَ

And in the heaven is your provision and whatever you are promised.

فَوَرَبِّ السَّمَاءِ وَالْأَرْضِ إِنَّهُ لَحَقٌّ مِّثْلَ مَا أَنَّكُمْ تَنطِقُونَ

Then by the Lord of the heaven and earth, indeed, it is truth - just as [sure as] it is that you are speaking.
