Al-Baqarah 2:203

Wathkuroo Allaha feeayyamin maAAdoodatin faman taAAajjala fee yawmaynifala ithma AAalayhi waman taakhkhara fala ithmaAAalayhi limani ittaqa wattaqoo Allaha waAAlamooannakum ilayhi tuhsharoon

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.

Recite the name of Allah during the given number of days. Then whoever is early in leaving after two days, there is no sin on him, and whoever leaves later, there is no sin on him, if he is God-fearing. Fear Allah and be sure that you are going to be gathered before Him.
