Assalamualaikum
I have read academic page on verse 30:1-10, al-Rum, according The paper is long and goes into great detail, but I will summarize just the first few pages, which I read.
The 4 readings are:
ġulibat al-Rūm … sa-yaġlibūna, “the Romans have been vanquished … they will van- quish”
ġalabat al-Rūm … sa-yuġlabūna, “the Romans have vanquished … they will be van- quished”;
ġalabat al-Rūm … sa-yaġlibūna, “the Romans have vanquished … they will win”;
ġulibat al-Rūm … sa-yuġlabūna, “the Romans have been vanquished … they will be vanquished.”
Is 7 or 10 reading of Quran, follow this reading(anyone of 4), if not then what this reading is about?
