Couplet 294-300

شاہ آں  خوں از پئے شہوت نکرد

The king didn’t do that killing for lust or greed

تو رہا کن بد گمانی و نَبَرد

You should stop doubting & disputing it

توگماں کردی کہ کرد آلودگی

You thought that he was indulged in his desires

در صفاغِش کے ہلد پالودگی

But how can cleaning leave the contaminants 

بہرِ آنست ایں ریاضت ویں جَفا

This work and struggle is for the purpose

تا بر آرد کورہ از  نکُرہ جُفا

That the contaminants be removed from silver in the hearth

بہرِ آنست امتہانِ نیک و بَد

The examination of pure and impure is for the purpose

تا بجوشد، بر سَر آرد زر زَبد

That the passion picks up & gold brings its impurities to top with froth

بگذر از ظنِّ خطا اے بَدگماں

O’ you doubter, leave the insinuations

  را بخواں    اِنَّ بَعْضَ الظَنِّ اِثْمُ 

And read “Indeed some doubts are sins”

گر نبودش  کار ز اِلہامِ اِلاہ

Had this work is not done through the intuition from Allah

اُو سگے بودے دَر انذہ نہ شاہ

He would have been a dog and not a king

پاک بود از شہوت و حرص و ہَوا

He (the king) is free from lust, greed and desires

نیک کرد اُو  لیکِ نیکِ بَدنما

 He did a good job, a good which looks like bad apparently

The killing done by the king was not for the lust or worldly desire. Thus you should leave the doubt and dispute regarding this, as you might be thinking that the king was involved in the sin. This doubt of yours is wrong, as the king had already been purified through the austerities (ریاضت) and how can cleansing leave impurities there in the process of cleansing. Since the bad attributes are not leaving easily and hence the struggles (ریاضت) and austerities (مجاہدات) are being practiced so that the bad attributes be separated from the good habits. This is like the hearth, which makes impurities be separated from the silver, only it needs to be melted and thus melting is akin to austerities (ریاضت) and separation of impurities from silver is like the purification of self after struggles and austerities. Therefore, you should be refrained from the doubting  and see what Allah Ta’ala has said (Quran 49:12):

Indeed, some assumption is sin

The examination of good and bad (whether the endeavors are by rule (شرعہ) or through genesis i.e. whether by self or by constraint) are due to the fact to see them separated from each other, like the gold when melted shows fervor and throw all the impurities at the top so that the same be removed and the gold will be purified. Thus if the action of the king is not according to the intuition (الہام), then he will be a worldly inclined dog and not a king. In fact, he was clean of lust & greed and whatever he had done is for good, though it looks bad outwardly/ apparently.
