Almuntakhab Fi Tafsir Alquran Alkarim

And by the visible mass of condensed watery vapour floating at various heights in the upper air

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(51:2) which carry clouds laden with water, *1

And those [clouds] carrying a load [of water] meaning

*1) All the commentators are agreed that adh-dhariyat implies the winds that disperse and mist up the dust, and al-hamilat-i wiqran implies the winds that Iift up millions of tons of water vapours from the oceans in the form of clouds. This same commentary has been reported from Hadrat `Umar, Hadrat `Ali, Hadrat 'Abdullah bin `Abbas, Hadrat `Abdullah bin `Umar, and also from Mujahid, Said bin Jubair, Hasan Basri, Qatadah, Suddi and other scholars.
