وَمَا كَانَ الْمُؤْمِنُونَ لِيَنْفِرُوا كَافَّةً ۚ فَلَوْلَا نَفَرَ مِنْ كُلِّ فِرْقَةٍ مِنْهُمْ طَائِفَةٌ لِيَتَفَقَّهُوا فِي الدِّينِ وَلِيُنْذِرُوا قَوْمَهُمْ إِذَا رَجَعُوا إِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ
It is not possible for all believers to go out (to fight). So a part of each section (of the population) should go (to fight) in order that the others may acquire understanding of law and divinity, and warn their companions on return so that they may take heed for themselves.
And the believers should not go forth to war all together. But why should not a party from every community of them mobilize to acquire profound, correct knowledge and understanding of religion and warn their people when they return to them so that they may beware (of wrongful attitudes)?
It is not possible for the believers to go forth (from their homes learning for religious learning) all together. Then, why should not a party from every section of them go forth, that they may (learn and) become well-versed in religion, and may warn their people when they return (home) to them, so that they too may guard against (unislamic ways of life).
With all this, it is not desirable that all of the believers take the field [in time of war]. From within every group in their midst, some shall refrain from going forth to war, and shall devote themselves [instead] to acquiring a deeper knowledge of the Faith, and [thus be able to] teach their homecoming brethren, so that these [too] might guard themselves against evil. 162
And it is not for the believers to march forth all together. So why should not a band from each party of them march forth so that they may gain understanding in religion and that when they come back unto them, haply they might warn their people when they come back unto them, haply they may beware!
And it is not possible for the Muslims that all of them go out; so it should be that a party from each group go forth in order to gain knowledge in religion, and upon returning warn their people in the hope that they may avoid.
The believers should not march forth altogether. If a section from every troop remain behind, then they could devote themselves to gaining sound knowledge of their religion and teach their people when they return to them, that per chance (or possibly) they may beware of evil.
And the believers were not to rush/hasten all (to battle) , so if only (there were) a group from every group/party from them, a group of people to learn/comprehend/have knowledge in the religion, and to warn/give notice (to) their nation if they returned to them, maybe/perhaps they be warned/cautioned .
It is not proper that the believers should go forth all together. Therefore, why not a squadron from each division stay behind so that they may obtain the understanding of Deen (Al-Islam), and admonish the people when they return to them so that they may refrain from un-Islamic conduct!
Nor spend they any thing, small or great, nor do they traverse a valley but it is written down for them, that Allah may reward them for the best of what they did.
Not all believers have to become specialists in religious learning. Why do not some people from each group of believers seek to become specialists in religious learning and, after completing their studies, guide their group so that they will have fear of God.
And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.
And it does not beseem the believers that they should go forth all together; why should not then a company from every party from among them go forth that they may apply themselves to obtain understanding in religion, and that they may warn their people when they come back to them that they may be cautious?
And it is not (proper) for the believers to go out to fight (Jihad) all together. Of every troop of them, a party only should go forth, that they (who are left behind) may get instructions in (Islamic) religion, and that they may warn their people when they return to them, so that they may beware (of evil).
Nor should the Believers all go forth together: if a contingent from every expedition remained behind, they could devote themselves to studies in religion, and admonish the people when they return to them,- that thus they (may learn) to guard themselves (against evil).
