وَلِكُلٍّۢ وِجْهَةٌ هُوَ مُوَلِّيهَا ۖ فَٱسْتَبِقُوا۟ ٱلْخَيْرَٰتِ ۚ أَيْنَ مَا تَكُونُوا۟ يَأْتِ بِكُمُ ٱللَّهُ جَمِيعًا ۚ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ
And each one hath a goal toward which he turneth; so vie with one another in good works. Wheresoever ye may be, Allah will bring you all together. Lo! Allah is Able to do all things.
