﴿ ٱللَّهَ رَبَّكُمْ وَرَبَّ ءَابَآئِكُمُ ٱلْأَوَّلِينَ ﴾

“God, your Sustainer and the Sustainer of your forebears of old?””

God your Lord and the Lord of your forefathers?’ read as predicates allāhu rabbukum and rabbu in the nominative because of the implicit omitted huwa being the subject; or read allāha rabbakum and rabba in the accusative as supplements to ahsana ‘the best of’.
