﴿ إِذْ قَالَ لِأَبِيهِ يَٰٓأَبَتِ لِمَ تَعْبُدُ مَا لَا يَسْمَعُ وَلَا يُبْصِرُ وَلَا يُغْنِى عَنكَ شَيْـًۭٔا ﴾

“when he spoke [thus] unto his father: "O my father! Why dost thou worship something that neither hears nor sees and can be of no avail whatever to thee?”

When he said to his father Āzar ‘O my father! the final tā’ here of abati has replaced the possessive yā’ of genitive annexation sc. of yā abī; the two however are never used together — he Abraham’s father used to worship idols. Why do you worship that which neither hears nor sees and is of no avail to you suffices you not in any way? whether in terms of benefit or harm.
