Al-Hijr - 15:14

وَلَوْ فَتَحْنَا عَلَيْهِم بَابًا مِّنَ السَّمَاء فَظَلُّواْ فِيهِ يَعْرُجُونَ
[15:14]
And even if We open to them a gateway of heaven, so that they ascend into it all the while,
Even if We opened out to them a gate from heaven, and they were to continue (all day) ascending therein,
And even if We opened unto them a gate of heaven and they kept mounting through it,
