Asslamualaikum,

Qur'an 36:40 is often quoted verse to Claim that Qur'an speaks of Celestial Movement in their orbits.

But i came over a problem which i found there which is Whether All Swim in Their own Orbits OR in a Single Orbit.

Here are different translations :

[ Muhsin Khan ]It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit.

Pickthall
It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit.


Only Yusuf Ali Translates according to the fact but still he uses brackets which shows that these words doesn't exist in Quran.

Yusuf Ali
It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law).



The word (36:40:14) "falakin" an orbit is N – genitive masculine indefinite noun according to Corpus Quran, means is Sigular,

So does it mean that Qur'an says that they All Move in ONE SINGLE ORBIT ?

and What does the word (36:40:12)wakullun "but all" means ?

Can you shed some light on it if you're aware of Arabic Language ?

Thanks.
