(21) And when you are among them and keep up the prayer for them, let a party of them stand up with you, and let them take their arms; then when they have prostrated themselves let them go to your rear, and let another party who have not prayed come forward and pray with you, and let them take their precautions and their arms; (for) those who disbelieve desire that you may be careless of your arms and your luggage, so that they may then turn upon you with a sudden united attack, and there is no blame on you, if you are annoyed with rain or if you are sick, that you lay down your arms, and take your precautions; surely Allah has prepared a disgraceful chastisement for the unbelievers.

(22) And whatever is in the heavens and whatever is in the earth is Allah's and certainly We enjoined those who were given the Book before you and (We enjoin) you too that you should be careful of (your duty to) Allah; and if you disbelieve, then surely whatever is in the heavens and whatever is in the earth is Allah's and Allah is Self-sufficient, Praise-worthy.

(23) O you who believe! do not violate the signs appointed by Allah nor the sacred month, nor (interfere with) the offerings, nor the sacrificial animals with garlands, nor those going to the sacred house seeking the grace and pleasure of their Lord; and when you are free from the obligations of the pilgrimage, then hunt, and let not hatred of a people-- because they hindered you from the Sacred Masjid-- incite you to exceed the limits, and help one another in goodness and piety, and do not help one another in sin and aggression; and be careful of (your duty to) Allah; surely Allah is severe in requiting (evil).

(24) They ask you as to what is allowed to them. Say: The good things are allowed to you, and what you have taught the beasts and birds of prey, training them to hunt-- you teach them of what Allah has taught you-- so eat of that which they catch for you and mention the name of Allah over it; and be careful of (your duty to) Allah; surely Allah is swift in reckoning.

(25) And remember the favor of Allah on you and His covenant with which He bound you firmly, when you said: We have heard and we obey, and be careful of (your duty to) Allah, surely Allah knows what is in the breasts.

(26) O you who believe! Be upright for Allah, bearers of witness with justice, and let not hatred of a people incite you not to act equitably; act equitably, that is nearer to piety, and he careful of (your duty to) Allah; surely Allah is Aware of what you do.

(27) O you who believe! remember Allah's favor on you when a people had determined to stretch forth their hands towards you, but He withheld their hands from you, and be careful of (your duty to) Allah; and on Allah let the believers rely.

(29) O you who believe! do not take for guardians those who take your religion for a mockery and a joke, from among those who were given the Book before you and the unbelievers; and be careful of (your duty to) Allah if you are believers.
