Quran Al-Baqarah 2:203
وَٱذۡكُرُواْ ٱللَّهَ فِيٓ أَيَّامٖ مَّعۡدُودَٰتٖۚ فَمَن تَعَجَّلَ فِي يَوۡمَيۡنِ فَلَآ إِثۡمَ عَلَيۡهِ وَمَن تَأَخَّرَ فَلَآ إِثۡمَ عَلَيۡهِۖ لِمَنِ ٱتَّقَىٰۗ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّكُمۡ إِلَيۡهِ تُحۡشَرُونَ ٢٠٣
Translation
And remember Allāh during [specific] numbered days. Then whoever hastens [his departure] in two days - there is no sin upon him; and whoever delays [until the third] - there is no sin upon him - for him who fears Allāh. And fear Allāh and know that unto Him you will be gathered.
