They wish that you would soften [in your position], so they would soften [toward you].
Tafseer
{ ودوا } تمنوا { لو } مصدرية { تدهن } تلين لهم { فيدهنون } يلينون لك وهو معطوف على تدهن، وإن جعل جواب التمني المفهوم من ودوا قدر قبله بعد الفاء هم.
{And they wish} they wished {if} a source {that you would be gentle with them} {that they would be gentle with you} and it is conjoined with “be gentle with you”, and if it is made the answer to the wish understood from “they wished” it is estimated before it after the “fa” they.
