۞ وَٱذْكُرُوا۟ ٱللَّهَ فِىٓ أَيَّامٍۢ مَّعْدُودَٰتٍۢ ۚ فَمَن تَعَجَّلَ فِى يَوْمَيْنِ فَلَآ إِثْمَ عَلَيْهِ وَمَن تَأَخَّرَ فَلَآ إِثْمَ عَلَيْهِ ۚ لِمَنِ ٱتَّقَىٰ ۗ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّكُمْ إِلَيْهِ تُحْشَرُونَ
Remember Allah through the appointed days. Then whoso hasteneth (his departure) by two days, it is no sin for him, and whoso delayeth, it is no sin for him; that is for him who wardeth off (evil). Be careful of your duty to Allah, and know that unto Him ye will be gathered.
