Allah said,

[فَاتَّقُواْ اللَّهَ مَا اسْتَطَعْتُمْ]

(So have Taqwa of Allah as much as you can;) meaning, as much as you are able and can bear or endure. The Two Sahihs recorded that Abu Hurayrah said that the Messenger of Allah said,

«إِذَا أَمَرْتُكُمْ بِأَمْرٍ فَائْتُوا مِنْهُ مَا اسْتَطَعْتُمْ، وَمَا نَهَيْتُكُمْ عَنْهُ فَاجْتَنِبُوه»

(When I command you to do something, do as much as you can of it, and whatever I forbid for you, then avoid it.) Allah's statement,

[وَاسْمَعُواْ وَأَطِيعُواْ]

(listen and obey,) means, obey what Allah and His Messenger command you to do and do not stray from it to the right or left. Do not utter a statement or make a decision before Allah and His Messenger issue a statement or decision. Do not ignore what you were ordered to do, nor commit what you were forbidden from doing.
