Allaah (subhaanah) said:

إِنَّ ٱلۡمُتَّقِينَ فِى جَنَّـٰتٍ۬ وَعُيُونٍ

ءَاخِذِينَ مَآ ءَاتَٮٰهُمۡ رَبُّہُمۡ‌ۚ إِنَّہُمۡ كَانُواْ قَبۡلَ ذَٲلِكَ مُحۡسِنِينَ

كَانُواْ قَلِيلاً۬ مِّنَ ٱلَّيۡلِ مَا يَہۡجَعُونَ

وَبِٱلۡأَسۡحَارِ هُمۡ يَسۡتَغۡفِرُونَ

وَفِىٓ أَمۡوَٲلِهِمۡ حَقٌّ۬ لِّلسَّآٮِٕلِ وَٱلۡمَحۡرُومِ

”Verily, the Muttaqoon (pious) will be in the midst of Gardens and springs (in the Paradise), taking joy in the things which their Lord has given them. Verily, they were before this Muhsinoon (good-doers). They used to sleep but little by night [invoking their Lord (Allaah) and praying, with fear and hope].   And in the hours before dawn, they were (found) asking (Allaah) for forgiveness, And in their properties there was the right of the beggar, and the Mahroom (the poor who does not ask the others).” [51:15-19]
