Surat Maryam (47-48)

{قَالَ سَلَامٌ عَلَيْكَ سَأَسْتَغْفِرُ لَكَ رَبِّي إِنَّهُ كَانَ بِي حَفِيّاً} (مريم: 47)

47- Abraham (peace be upon him) said to him: Peace be upon him, you shall not be harmed by me, father. I shall invoke Allah to guide you to the truth, guide you to repentance, and forgive your sins as long as I am alive. Indeed, my lord is so Kind where He honored me and guided me to worship Him and devote myself to Him.

Abraham (peace be upon him) did not invoke Allah for his father after he had known that he died as a polytheist: "And Ibrâhîm’s (Abraham) invoking (of Allâh) for his father’s forgiveness was only because of a promise he [Ibrâhîm (Abraham)] had made to him (his father). But when it became clear to him [Ibrâhîm (Abraham)] that he (his father) is an enemy of Allâh, he dissociated himself from him." [Surat At-Tawbah: 114]

{وَأَعْتَزِلُكُمْ وَمَا تَدْعُونَ مِن دُونِ اللَّهِ وَأَدْعُو رَبِّي عَسَى أَلَّا أَكُونَ بِدُعَاء رَبِّي شَقِيّاً} (مريم: 48)

48- I will stay away from you and free myself of you and of your gods which you are worshipping, O polytheists, and I shall worship my lord who is one true god. I hope to worship Him as should and He accepts my worship by His Generosity. These words show good manners with Allah, and indicating the wretchedness of those who worship gods.
