Ayat Tafseer
Ghamidi Sahab translation of the word in Al-Bayan They had only been directed to worship God, obeying Him exclusively with full devotion, diligently adhere to the prayer and pay zakāh. This is the religion of the Upright Nation. [10] (98:5). Commentary: [10] The actual words are: ذٰلِكَ دِيۡنُ الۡقَيِّمَةِ. Their actual construction is: دين الملة القيمة. The noun qualified by the attribute قَيِّمَة has been suppressed in accordance with linguistic principles. The upright nation refers to the nation of Abraham (sws). The implication is that these clear directives were given to both branches of Abraham’s progeny as the collective heritage of their forefather. The Torah also preached them. The Qur’ān too is giving them the same directives. So what guidance are they now waiting for and what types of directives do they now desire? The religion of God has always remained the same, but which of its directives have they adhered to? The divisions which they are in have made them lose every element of religion. Ghamidi Sahah further quotes his teacher for elaboration if you want to read more in the commentary of the link given below. Source.
