Sahih International
And they swear by Allah their strongest oaths that if you ordered them, they would go forth [in Allah ‘s cause]. Say, “Do not swear. [Such] obedience is known. Indeed, Allah is Acquainted with that which you do.”
Muhsin Khan
They swear by Allah their strongest oaths, that if only you would order them, they would leave (their homes for fighting in Allah’s Cause). Say: “Swear you not; (this) obedience (of yours) is known (to be false). Verily, Allah knows well what you do.”
Pickthall
They swear by Allah solemnly that, if thou order them, they will go forth. Say: Swear not; known obedience (is better). Lo! Allah is Informed of what ye do.
Yusuf Ali
They swear their strongest oaths by Allah that, if only thou wouldst command them, they would leave (their homes). Say: “Swear ye not; Obedience is (more) reasonable; verily, Allah is well acquainted with all that ye do.”
Shakir
And they swear by Allah with the most energetic of their oaths that if you command them they would certainly go forth. Say: Swear not; reasonable obedience (is desired); surely Allah is aware of what you do.
Dr. Ghali
And they have sworn by Allah their most earnest oaths (that) indeed in case you command them, indeed they will definitely go out. Say, “Do not swear (i.e. He recognizes your failure to obey). Beneficent obedience (is better). Surely Allah is Ever-Cognizant of whatever you do.”
