My Lord, indeed they have led astray many among the people. So (14:36)

Almuntakhab Fi Tafsir Alquran Alkarim

These objects of worship O Allah, my Creator, have allured the minds eyes of the many who strayed from. Your path of righteousness, therefore, he who follows me and submits to Your system of faith and worship shall be an integral part of me, and he who disobeys me shall be left to plead his causes and You decide them; you are Ghafurun (Forgiving) and Rahimun (Merciful)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(14:36) Lord! these have turned away *48 many people from the Right Way (and they might turn away my descendants as well. Therefore, only those of them) who follow my way, belong to me, but (I leave to Thee) those who follow a different way from mine, for Thou art very Forgiving and Merciful. *49

My Lord, indeed they have led astray many among the people. So meaning

*48) This is a figurative way of saying that idols have been the means of turning many people away from Allah's Way into the ways of deviation.
*49) This forbearance shown towards those who followed a different way from the Right Way is an instance of Prophet Abraham's leniency to mankind. He left their case to the Forgiveness and Mercy of Allah for he could not bear to see them under Divine scourge. Another instance of this has been cited in Surah Hud. When the angels were on their way to destroy the wicked people of Lot, Prophet Abraham began to plead for them: " .... Abraham began to dispute with Us concerning the people of Lot for he was tender-hearted and merciful...."(XI: 74-75) Likewise Prophet Jesus was so tender-hearted that even when Allah will show to him that his followers had deviated from the Right Way, he will plead their case: "Now if you punish them, they are your own servants, and if you forgive them, you are All- Mighty and All-Wise" (v: 118).

پروردگار، اِن بتوں نے بہتوں کو گمراہی میں ڈالا ہے (ممکن ہے کہ میری اولاد کو بھی یہ گمراہ کر دیں، لہٰذا اُن میں سے) جو میرے طریقے پر چلے وہ میرا ہے اور جو میرے خلاف طریقہ اختیار کرے تو یقیناً تو درگزر کرنے والا مہربان ہے
