تِلْكَ حُدُودُ ٱللَّهِ ۚ وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُۥ يُدْخِلْهُ جَنَّٰتٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَا ۚ وَذَٰلِكَ ٱلْفَوْزُ ٱلْعَظِيمُ
These are the limits (imposed by) Allah. Whoso obeyeth Allah and His messenger, He will make him enter Gardens underneath which rivers flow, where such will dwell for ever. That will be the great success.
