Yusuf Ali
Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into (the hearts of) the enemies, of Allah and your enemies, and others besides, whom ye may not know, but whom Allah doth know. Whatever ye shall spend in the cause of Allah, shall be repaid unto you, and ye shall not be treated unjustly.

Sahih International
And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows. And whatever you spend in the cause of Allah will be fully repaid to you, and you will not be wronged.

Shakir
And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah´s way, it will be paid back to you fully and you shall not be dealt with unjustly.

Pickthall
Make ready for them all thou canst of (armed) force and of horses tethered, that thereby ye may dismay the enemy of Allah and your enemy, and others beside them whom ye know not. Allah knoweth them. Whatsoever ye spend in the way of Allah it will be repaid to you in full, and ye will not be wronged.

محمد جالندھری
اور جہاں تک ہوسکے (فوج کی جمعیت کے) زور سے اور گھوڑوں کے تیار رکھنے سے ان کے (مقابلے کے) لیے مستعد رہو کہ اس سے خدا کے دشمنوں اور تمہارے دشمنوں اور ان کے سوا اور لوگوں پر جن کو تم نہیں جانتے اور خدا جانتا ہے ہیبت بیٹھی رہے گی۔ اور تم جو کچھ راہ خدا میں خرچ کرو گے اس کا ثواب تم کو پورا پورا دیا جائے گا اور تمہارا ذرا نقصان نہیں کیا جائے گا
