عَنْ حَبِيبِ بْنِ حِمَازٍ الأَسَدِيّ قَالَ : أَتَى رَجُلٌ فَسَأَلَ عَلِيّا وَأَنَا عِنْدَهُ عَنْ ذي الْقَرْنَيْنِ فَقَال : هُوَ عَبْدٌ صَالِحٌ نَاصِحٌ لِله فَأطاعَ الله فَسَخّرَ لَهُ السّحَابَ فَحَمَلَهُ عَلَيْهِ وَمَدّ لَهُ في الأَسْبابِ وَبَسَطَ لَهُ فِي النّور On the authority of Habib b. Himaz al-Asadi, he said, “A man came and asked Ali, whilst I was with him, about Dhu al-Qarnayn, and he said, ‘He was a righteous and sincere servant of God, he obeyed God and God subjugated for him the clouds and carried him upon them, and gave him the means [to travel vast distances], and gave him increase in light.'” – Tafseer Abd al-Razzaq

Did you know…

The primary meaning of سَبَب is rope, and particularly one suspended from a high place, used for climbing; it is in this latter sense that the Quran uses the word in the above-mentioned verse. Because the rope is the means by which one can get from one point to another otherwise inaccessible point, it is used by extension to mean cause, means.
