it is not fitting for a believing man or woman to exercise any choice in his or her own affairs once god and his messenger have reached a decision upon them. anyone who disobeys god and his messenger is in manifest error.
وما كان لمؤمن ولا مؤمنة إذا قضى الله ورسوله أمرا أن يكون لهم الخيرة من أمرهم ومن يعص الله ورسوله فقد ضل ضلالا مبينا
